I feel miserable and trapped in a loop!

I’m trapped in a health OCD loop, I had a minor infection that was cleared up with antibiotics and everything, but my ocd fixated on it, and because of me hyper focusing on that area of my body the muscles there have become all screwed up from being constantly tensed

and it’s been months and I can no longer tell what’s an actual worrying sensation or a result of my hyper fixating on every minor sensation and also myself muscles just hurting

And I’ve been working with my therapist and psychiatrist but I keep getting trapped by wondering if it’s an actual physical problem or all in my head

I’m so miserable and tired, has anyone else experienced something similar?
