I had an exacerbation after riding my electric bike easy for 20 minutes. I'm on Prednisone 10mg for 5 days and have not improved . I'm supposed to cut back to 5 tomorrow. Than 5 every other day. I was out of breath taking a shower today. It was a little worse than the last one(2 days ago haha). Should I have more patience ? Am I suppose to rest or be somewhat active ? I seem to be going down hill fast.
