Thank you both for responding!
I was doing quite a bit better after the zantac/zyterx and was to the point I could get to my home office upstairs without getting short of breath. About 2 days after the shots (1 in each ankle) my symptoms exploded. I don’t have the energy to even leave the house, let alone go upstairs to my office. My heart rate is erratic, I have constant headaches and nausea. I think I had mild POTS since I was 16 (now 46) but for the most part I was functioning fairly well. Then a couple of years ago I started getting a lot of injuries with ligament tears and ended up getting a lot of shots. I don’t remember the shots doing much then, but last Jan. I was getting a huge number of shots (2-3 every visit) due to a bad ankle injury that wasn’t healing. I am pretty sure that is where my decline began. By April I was incapacitated for the most part. I was just starting to get some semblance of a life back then a couple of weeks ago I got 2 shots and feel like my symptoms are out of control again. I will be weighing very heavily the pros and cons of corticosteroids next time. I think I would much rather deal with the pain.
