I am on a 6 week course of Prednisolone lowering my dose each week. I am on week 2 now last week I was on 15mg this week 10mg! As soon I went onto 10mg I got a sore type of pain near my right armpit didn't think of it much but now it's spreading and even more sore like a bruise hurts to move and touch. It's all the way from my armpit to just below my elbow and now also on my hand and wrist. But it does not look bruised. I am confused has anyone experienced this before?
