Painful periods: the complete guide to natural cycle relief
The essentials in 30 seconds.
In France, 1 in 2 women suffers from painful periods, and 1 out of 10 considers them intolerable. It's not normal, and it's not inevitable.
Menstrual pain has a precise mechanism: uterine contractions triggered by the prostaglandins, These reduce pelvic microcirculation and create local ischemia - exactly the same phenomenon as an intense muscle cramp.
The patch STIMCARE Periods acts as an infrared mirror, stimulating local microcirculation and activating the natural production of'nitric oxide (NO), physiological vasodilator - Nobel Prize in Medicine 1998.
Applied according to a 3-point protocol, it supports menstrual comfort drug-free, hormone-free, with no effect on your contraception.

You know they're coming. You recognize the first signs - that tension in your lower abdomen, the pulling in your back, the fatigue that sets in.
You also know that for two to five days, you're going to slow down. Cancel maybe. Take anti-inflammatories, probably. And hear, once again, that «it's normal» or that «it'll pass eventually».
The truth is menstrual pain has a precise biological explanation, and can be modulate it.
This guide gives you everything you need to know: the science behind menstrual pain, what triggers it, what can soothe it, and how STIMCARE Periods is part of a holistic approach - drug-free and hormone-free.
Painful periods: 1 in 2 women suffer - and we don't talk about it much
In France, 15 million women are of menstruating age. One in two has painful cycles. One in ten finds them intolerable.
For teenage girls, the figures are even more telling: 30 to 50 % miss at least one day of school a month because of their periods. And the average age of first diagnosis of'endometriosis is still 27 years, after an average 7 years of medical wandering.
And yet, menstrual pain remains largely unmarked. How many times have you heard - or thought - that 'there's nothing you can do about it«, that »all women go through it«, or that »you just have to take it in your stride'?
This trivialization is not innocent: it delays diagnosis, deprives women of solutions, and sustains a culture of silence that benefits no one.
Pain that recurs, that disrupts your life, that resists basic analgesics, deserves to be taken seriously and supported. Not tolerated.
Primary vs. secondary dysmenorrhea: understanding the difference
The medical term for «painful periods» is dysmenorrhea. Doctors distinguish between two main categories, and the distinction is important: it changes the way we manage our patients.
| Primary | Secondary | |
|---|---|---|
| Appearance | In the first few years after menarche | Later (often after age 30), or progressive worsening |
| Cause | No anatomical cause - prostaglandins + uterine contractions | Underlying pathology: endometriosis, adenomyosis, fibroids, PCOS, misplaced IUD, pelvic infection |
| Typical profile | Women aged 15-30, pain in the 1st days of the cycle | More intense, longer pain, may spill over outside the period |
| Warning signs | Stable pain from one cycle to the next | Heavy bleeding, pain outside the period, pain during intercourse |
The menstrual cycle in 4 phases: where to place the pain
To understand when and why pain occurs, we need to visualize the cycle as a whole. On average, a cycle lasts 28 days and is divided into four clearly defined hormonal phases.
Menstrual pain is not not evenly distributed on the cycle: it is concentrated on the first 24 to 72 hours of menstruation, sometimes on the first day alone. This is precisely the window we need to target to take effective action.
Why does it hurt? The mechanics of prostaglandins
At the time of menstruation, the uterine lining (the'endometrium), which had thickened throughout the cycle, becomes detached and must be removed.
For this elimination to take place, the uterus must contract - like a muscle pushing out what's inside.
These contractions are triggered by chemical mediators called prostaglandins, released by the endometrium. The more a woman produces, the stronger her contractions - and the more intense the pain.
The exact mechanism of pain lies in three stages :
- Intense uterine contraction The myometrium contracts strongly to expel the endometrium.
- Local ischemia contractions compress the vessels that supply the uterus, creating a transient deprivation of oxygen - just like a calf cramp.
- Nociceptor stimulation Oxygen deprivation and the accumulation of cellular waste activate pain receptors.
That's why menstrual pain resembles intense muscle cramps - because it are.
And that's why any action that improves local microcirculation is likely to reduce pain: by restoring oxygen supply, we cut the chain at source.
Nitric oxide and microcirculation: the natural way to relief
Your body already has a natural system for managing microcirculation: the production of'nitric oxide (NO).
It's a gas that blood vessels produce themselves to dilate and let more blood through. This discovery earned the Nobel Prize in Medicine in 1998 to researchers Furchgott, Ignarro and Murad.
NO is synthesized on demand by an enzyme called eNOS (endothelial nitric oxide synthase) located in the inner walls of blood vessels. When activated - by exercise, heat or certain nutrients - it produces NO locally.
NO relaxes vessels and improves circulation. More blood circulates, more oxygen arrives, less cramp.
This is exactly the mechanism STIMCARE Periods exploited - with no hot water bottle, no artificial heat, and total autonomy.
STIMCARE Periods: eNOsyntex technology applied to the cycle
STIMCARE Periods is a Class I medical device (CE marking, MDR 2017/745). The patch is a infrared mirror It contains no drugs, hormones or active ingredients. Nothing penetrates the skin.
Its principle is purely physical and physiological. The patch contains inert metal oxides which reflect the natural infrared rays emitted by your body (4 to 20 microns) and send them deep into the environment, up to 40 to 50 millimetres under the skin. This infrared stimulation activates your eNOS enzyme, which produces NO locally, dilating vessels, improving pelvic microcirculation - and ultimately reducing pain in the same way as a hot water bottle, but continuously and without equipment.
Technology is passive: it activates your own mechanisms without adding anything to the body. This makes it compatible with all contraceptions, all current treatments, and all profiles - with the exception of the cases mentioned below (pregnancy, allergy to natural latex).
The 3-point protocol: where to apply the patches
STIMCARE Periods uses an en 3 points, designed to cover the main areas of menstrual pain.
Lower abdomen
2 to 3 cm below the navel, centred on the midline. The main patch: acts directly on the uterine zone to relieve central pelvic cramps.
Lower back
In the sacred region, just above the coccyx. Targets radiating lumbar pain and complements the action of the belly patch with symmetrical stimulation.
Ovarian point
À halfway between the iliac spine and the pubis, on the most painful side. If both sides are affected, alternate from one cycle to the next.
The complete protocol therefore uses 3 patches per cycle. A box of 6 patches covers 2 cycles; a box of 16 patches covers approx. 5 cycles.
When to start? How long before it takes effect?
The ideal is to apply the patches 24 to 48 hours before the first day of menstruation, The patches are designed to stimulate microcirculation by the time uterine contractions occur. In practical terms, as soon as you recognize the warning signs (tension in the lower abdomen, breast tenderness, unusual fatigue), you apply the patches.
If you discover the patch during your period, apply it anyway - the effect is still noticeable, just less anticipated. Most women experience a reduction in the first 30 minutes, with amplification over the following 2 to 3 hours.
The patch remains active 8 to 10 days, This more than covers the duration of the period and the return to normal.
Clinical results: what the figures say
In-house clinical studies of STIMCARE Periods in women with primary dysmenorrhea show consistent results:
- 100 % of women experience at least a slight reduction in pain after the first cycle of use.
- 87 % report a significant reduction menstrual pain.
- 0 % of respondents with no effect - an exceptional result for a non-medicated device.
- Several participants report complete disappearance of pain after 2 or more consecutive cycles of use.
These results are part of a broader scientific literature on passive thermotherapies and infrared textiles, which, for over 20 years, have demonstrated efficacy comparable to that of NSAIDs (non-steroidal anti-inflammatory drugs) on menstrual cramps, without the gastrointestinal side-effects of the drugs.
Endometriosis, adenomyosis, PCOS: what the patch can and cannot do
Menstrual pain may conceal pathologies that merit diagnosis and specialized treatment:
- Endometriosis endometrial tissue outside the uterus. Affects around 10 % of women of childbearing age. Causes intense, sometimes incapacitating pain.
- Adenomyosis Endometrial cancer: presence of endometrium in the uterine muscle itself. Often under-diagnosed in women aged 35-50.
- PCOS (polycystic ovary syndrome): hormonal imbalance leading to irregular and sometimes painful cycles.
- Uterine fibroids benign tumours of the uterine muscle, common and sometimes painful.
Precautions and contraindications
- Pregnancy the patch is not recommended for pregnant women, due to the lack of specific studies in this population. If you discover that you are pregnant during use, remove the patch and tell your doctor.
- Latex allergy The glue in the patch contains natural latex. In the event of a known allergy, the patch is not recommended.
- Injured skin Never apply the patch to open, irritated or actively lesioned skin.
- Abnormal bleeding If your periods suddenly become heavier or longer, or are accompanied by new pains, consult your doctor before using any device.
FAQ - Your most frequently asked questions
When should I start patching in my cycle?
Ideally 24 to 48 hours before the first day of your period, The microcirculation is already stimulated at the moment of contractions. If you discover the patch during your period, you can apply it at any time - the effect remains perceptible.
How many patches are needed for a complete cycle?
3 patches One on the lower abdomen, one on the lower back, one on the ovarian points. A box of 6 patches covers 2 cycles. A box of 16 patches covers approximately 5 cycles.
Is the patch effective from the first cycle?
Yes, in most cases. Internal studies show that 100 % of women experience at least a slight decrease in their first cycle, and 87 % a significant reduction. Some see the effect amplified over 2 to 3 consecutive cycles.
Can I use it if I'm on the pill?
Yes. The patch contains no drugs, no hormones, and nothing penetrates the skin: there is no possible interaction with oral contraception, implants or any other hormonal method.
Can the patch replace my anti-inflammatories?
The patch is not a drug and is not a substitute for prescribed treatment. Many women find they need less NSAIDs when using it - but this decision should always be made with your doctor.
Is it compatible with an IUD?
Yes, totally. The patch acts on the surface of the skin's microcirculation, and does not interfere with the position or mechanism of the IUD (copper or hormonal).
What if I also have endometriosis?
Endometriosis requires specialized medical care that nothing can replace. The patch can help reduce cyclical pain as a complement to your treatment, but it does not treat the disease. Talk to your gynecologist before use.
Is the patch waterproof? Can I swim?
Yes. The patch shower- and bath-proof. It stays in place for at least 3 days, and remains active for 8 to 10 days. Swimming pools and the sea are compatible, although prolonged exposure to chlorinated water can accelerate detachment.
Are there any side effects?
No possible drug effects (nothing penetrates the skin). The only known risk is a allergic reaction to natural latex contained in the glue. The patch is not recommended for pregnant women.
How much does STIMCARE Periods cost?
The box of 6 patches (2 cycles) is priced at 20.90 € INCL. VAT. The box of 16 patches (≈ 5 cycles) is available at 42.90 € INCL. VAT. Free shipping. The device is not reimbursed by Social Security.
