I have been taking pred 20mg for 4 weeks. I was diagnosed after a long drawn out process of tests etc that I can see from this is not unusual. My doctor is very good and is following guidelines to reduce so have been on 17.5 since Tuesday this week. The pains have started to return albeit not as bad as they were in the beginning. Would you suggest I persevere on 17.5 or go back to the doctor now to discuss?
