You can predict it, and nobody asked
You know the flare is coming before it arrives. The week before your period, the same sites start to ache. Sometimes it is a day or two after ovulation. It settles as you bleed, or shortly after, and then you get a clear stretch, and then it starts again. You may have noticed it went quiet in pregnancy, or that it changed after a contraceptive was started or stopped.
You have probably mentioned this to a doctor and watched it not be written down. It should have been. It is the single most useful thing you know about your disease.
What the pattern is telling you
HS is a systemic condition expressing through the skin — follicular occlusion driven by gut dysbiosis, immune dysregulation, hormonal signalling and insulin resistance. When your flares track your cycle, they are telling you which of those drivers is loudest in your case.
Androgen signalling affects the follicular unit directly: it alters keratin production and how the follicle behaves, and the follicle is where HS begins. Progesterone and oestrogen shift across the cycle, and the late luteal phase — the premenstrual window — is when that balance moves in the direction the follicle likes least. It is not a coincidence that this is when your sites hurt.
And androgens do not act alone. Insulin resistance raises free androgen availability, which is exactly why HS, PCOS and insulin resistance travel together so often. If you have HS plus irregular or absent periods, adult acne along the jaw, unwanted coarse hair growth, scalp thinning, weight that will not move, or a PCOS diagnosis already, you are not carrying several unrelated problems. You are carrying one driver with several outputs, and the HS is the loudest of them.
What it gets called instead
Hormonal HS is misread constantly. The lesions are called boils, infected cysts, ingrown hairs, folliculitis. When they sit in the groin they get swabbed for sexually transmitted infection. When they sit under the breast they get called sweat rash. The premenstrual timing gets attributed to "hormonal acne" or dismissed as ordinary premenstrual misery. Antibiotic courses are given, they work, and then they stop working — and nobody joins the pattern to the calendar.
Why previous treatments did not hold
Structural, not a criticism of anyone who treated you. Antibiotics reduce bacterial load and disrupt the microbiome, which is itself one of the drivers. Steroids and biologics suppress the immune signal without correcting why it misfires. Hormonal medication can genuinely help by damping the androgen signal — but it works on the signal, not on the insulin resistance and gut environment amplifying it, which is why the effect so often fades or does not survive stopping. Surgery removes lesions, not the environment that produced them.
What root-cause correction addresses here
This is the driver profile that responds most clearly, because there is a specific, correctable mechanism underneath rather than a vague one.
Phase L, Inflammatory Load Reduction (oral), takes down the inflammatory pressure so the premenstrual window stops escalating into abscesses. Phase I, Internal Correction (oral), is the centre of the work in hormonal HS — the gut, immune and metabolic environment that determines how much free androgen is circulating and how strongly the follicle reacts to it. Phase F, Functional Clearance (oral), clears accumulated load, and is only started once L and I are stable; brought forward, it mobilises load faster than the system can clear it and the disease worsens. Phase E, External Tissue Repair, is a topical applied at home. Phase S, Remission Maintenance, is a tapered oral phase across six to twelve months, which in cyclical disease matters because your body will keep testing the correction every single month.
There is no procedure and no clinic visit at any stage.
Track your cycle and your flares together and bring that with you. In hormonal HS, the first sign of change is usually not that lesions vanish — it is that the premenstrual flare gets smaller, or arrives and then fails to build.
What may not fully reverse
Correcting the driver changes what happens next. It does not undo what has already been built. Established sinus tunnels are structural rather than inflammatory and may not fully close, though they can quieten and shrink. Scarring and the dark, thickened skin left by years of cyclical flares can soften over a long period, but scarred skin does not become normal skin. And if your disease has reached EPOH-DSS Stage 4, advanced tunneling, full remission may not be achievable even with the hormonal driver corrected. You should hear that up front.
Staging
EPOH-DSS Stage 1 early nodular, EPOH-DSS Stage 2 inflammatory, EPOH-DSS Stage 3 sinus, EPOH-DSS Stage 4 advanced tunneling — mapping onto Hurley I to III. Treatment response is a separate scale: Recovery Stage 1 internal shift, Recovery Stage 2 reduced frequency, Recovery Stage 3 reduced severity, Recovery Stage 4 stable remission.
Your next step
Consultation is by video or WhatsApp. Bring your cycle history, any PCOS or insulin investigations, and photographs. Formulations are couriered to you and everything is done at home. If you are on hormonal medication, keep taking it — the plan is built around it, not against it, and any change is a conversation with your prescriber.
