I still have the ear problem. There is nothing they can do except puncture the ear drum. He is saving that as a last resort. In the mean time my head feels triple the size and I can not hear well. I increased my walking from 240 feet to 300 feet yesterday. I was sob but maybe it will get better if I keep doing it. I would still like to know how long it takes to recover from an exacerbation. It started Jan 13, well a week before that but I went to the hospital on the 13th.
