I tested positive on June 29 of this year. I had the same symptoms after I had COVID. The symptoms lasted for about a week after I finally tested negative. Now, after about three weeks post COVID I began having pain in my upper back and sides when inhaling. I had to go to an urgent care clinic. The doctor believes it is due to inflammation caused by COVID. The chest X-ray was normal. I was prescribed Naproxen and Prednisone. I've been on the medications for two days and I'm still having pain upon inhaling, although it's a little better.
