I was given a prescrip for 60mg a day of pred from a hospital ER in NYC. No tapering instructions were given, either. 4 days in I developed severe joint pain in wrists, knees, shoulder, etc. Day 6 I stopped cold turkey. Saw an allergist specialtist on Day 10 because this all started as a reaction I had to something still unknown. Yesterday on day 12 with no decrease in joint pain I started the pred again at 10mg at the doc's request. Pain got better a few hours later but then started again in my wrist which had previously cleared up. Took another 10mg before bed last night. Still lots of wrist pain. Today it's unbearable. Doc says to only take 5mg next time in am and 10 at night. I can't stand this pain! Advil won't make it decrease at all. Seems like I got relief when I started up the pred again but seems like I have a reaction to taking it again.
