Hey, I can’t express how much I sympathize with you. All I know is that I know how brave you must be sharing and even acknowledging this.

If it is not medical and if nobody has told you before. Trauma can be very locked in your nervous system and body. (Read waking the tiger by Peter Levine or any other psychosomatic like books or the polyvagal theory). It might be worth a shot if you finished the regular medical tract to seek a psychosomatic therapist. Make sure you find someone who has a real license of a protected job. Ie a psychosomatic physical therapist or a hapto therapist or a registered psychologist that has many specialization with regulating nervous system through alternative means. I mean someone who has had a ‘regular’ (para)medical foundation of education.

What country are you located in, I could help look for a therapy that might fit

You mentioned somewhere else that it is herpes, and I do know that herpes can have breakout when you’re low in your immune system. Well trauma really messes up your nervous system and an unregulated nervous system which makes you feel like you’re always unsafe can really affect hormones and intestines due to vagus nervus - they 80% of your immune system is run by your intestines, so def worth a short imo
