Patients have told me that exercise often exacerbates their condition. Certainly, I have been told that running and hiking can make epididymitis worse. Weight lifing may be a risk factor for epididymitis, although I have not had time to track down the literature on this issue in a definitive way. I would suggest swimming. See if you can do it without causing a worsening of symtoms. You can mimic weight lifing by doing the butterfly stroke. My best.
