The nerves at the entrance are the problem, and they are measurable. The nerve endings in the vestibule, the ring of tissue at the vaginal opening, have multiplied and lowered their firing threshold, so a cotton swab feels sharp ¹. The pelvic floor muscles tighten in guarding and the nervous system turns up the volume, which is why it clusters with fibromyalgia, IBS, and bladder pain syndrome ². One common trigger: a combined pill started in your teens or twenties thins the tissue in women with certain genes ³.

Two treatments carry the first line, and both beat their comparison. Pelvic floor physical therapy dropped intercourse pain about 79% at six months against 35% for the most-prescribed cream, lidocaine; 71% hit meaningful improvement ⁴. Sex-pain talk therapy beat a topical steroid, and the gains held ⁵. Surgery to remove the painful ring has the largest effect, 70 to 90% much-improved, but it is irreversible and last ⁶. Nerve-pain pills are the weak spot: gabapentin and desipramine both lost to a sugar pill ^{7 8}.

The order a specialist runs it, stacking pieces rather than trying one at a time.

Most of the shift lands in the second to fourth month. The swab stops flinching you. A long meeting stops running the "how bad is it today" monologue underneath it. Jeans you wrote off go back on.

• Six months: intercourse pain down about 79% in the physical therapy arm ⁴.
• The mood drop often lifts with the pain; women with vulvodynia are about four times as likely to be depressed, and much of that is the pain talking ⁹.
• Honest ceiling: substantial improvement is common, full remission less so.
