Kalinka,yes it seemed to resolve on its own from what i remember i am post meno too, and was at the time,have you googled the cause?
At the hospital where I eventually ended up they said that no one really knows the cause, hardly anyone gets better, and there's no point trying to do anything about it. I've read more sense here than I heard in hours of CBT.
The hospital doctor I saw initially was encouraging, prescribed Nortriptyline and Lidocaine ointment and said she thought it would sort itself out. About a month later I had to go to a group session in the same department of the same hospital, where we were given the complete opposite information - hardly anyone recovers, etc.etc. The negativity was psychologically very damaging, and up to that point I'd been starting to feel a bit better. If I hadn't gone to the session and the subsequent CBT, they'd have discharged me.
For me it was caused by the dentist starting a root canal treatment, grinding the tooth down until there was a tiny bit left, which was tearing my tongue to shreds. She said that she would have to leave it like that for three months before completing the treatment, though I went back twice and explained the problem. I changed to a different dental practice, where they did complete the treatment and crowned the tooth, but by then the pain had spread to other areas of the mouth.
Sorry, that's quite long!
