I got poison ivy rash starting in May, I treated myself in the beginning but didn t work, then went to a doctor. I was give Prednisone twice. First session was 12 days (40mg for 3, 30mg for 3, then 20mg for 3, then 10mg for 3), when I was in the last day of 10mg, the rash rebounded and all itch started again. Now I was taking my second round of Prednisone (16 days), I m in the last 6th days (20mg for 1 more day, and then 10mg for last 5 days). It seems when I tapered down to 20mg, the itch started and my knee swelled (much less than last time). I felt a bit difficulty when I walked. My question is: the poison ivy or Prednisone should not impact my bone, or my nerve, is that right? Thank you!
