Since your primary care physician seems to be at a loss for what is causing all your symptoms, I think you should probably ask him to refer you to some other doctor (a specialist) in muscular issues, urology (since you mentioned a problem in this area), and perhaps another sort of specialist. Have you had any other tests besides blood work? Any Cat Scan, MRI's, regular X-rays, etc.? You mention that your symptoms all began 3 days after vaccination. What vaccination are you referring to? The Covid vaccine or something else? It would seem a specialist (or a couple of them) is in order and that your primary care physician should be able to point you in the right direction.
