Hello, I am asking about my 82 year old father who has copd, high blood pressure, congestive heart failure... had a bout of gout and was put on prednisone. Took it this evening and is now complaining of wrist pain and leg pain on right side and knee pain on left. Could it be a side effect of the prednisone? Do you think it could be serious or could we wait to take him to the doctors in the morning? Thank you for taking the time to answer my question.
