Anyone get multiple mylenoma from prednisone? Just wondering, have to get blood test Friday, having lot of pain kidney area, but think from rare spinal surgery had in NYC. Sed. rate, and CRP been good (get blood every 3 weeks) plus no longer anemic so really think it is nothing to worry about. Was just wondering as see where it can be side effect of Prednisone. Been on heavy doses since Dec. 2014 down to 35 mg now.
