I am so sorry to hear that you are having this trouble. Are you feeling better now on the higher dose of steroid? With my asthma, I have had this happen to me before, where I was having trouble breathing and the lower dose of steroids just didn't quite cut it -- so a higher dose was needed. For me, 40 mg works well. I usually take it 3-5 days and it "usually" works like a charm. So, hopefully it works for you too. I say "usually" because sometimes I have to stay on it longer to get over my flare-ups. So, if you aren't feeling better after 3 days, don't hesitate to contact your doctor once again. Yes, it can be frustrating I know. I'm not your doctor, so I can't really give you advice whether or not to exercise while you are feeling this way. But, when I'm on steroids, I usually try to take it easy. And once I start feeling better, I try to get back to my workouts -- although I gradually phase it back in. I do hope you find this brief reply helpful. John. community moderator.
