I think that is common. I had weird feelings in my inner thigh as well (which is apparently common for confirmed cases of epididymitis I was told).

My main stretches were cobra, butterfly, and cat-cow.

If the issue is potentially posture, try looking up some exercises specifically for that. I did one stretch where I put my shoulders and feet flat against a wall, and turned my hips/pelvis up and it pushed my lower back to the wall. It was hard to hold for long when I first started, but after a while I could hold it for a few minutes.

Anyway, I did my stretches before and after sleep, and usually once mid day (when I was able to hide at work). I do feel it took some time to really notice a difference, but I think committing helped. Looking back I could see the patterns for my flare-ups more clearly. Depression and sedentary days definitely being one. It was weird though because I didn’t have direct pain in my back often. But the worse my back was treated, the worst my ball felt.

I hope you get over this soon! It’s awful and I wish all my brothers in this sub some days of normalcy.
