I am a 71 year old woman. I had Polio at almost 3 yrs old and also was diagnosed with multiple sclerosis at the age of 23, although I d had several episodes since i was 18, that were, in hind sight, exacerbations of M.S. The last 15-18 yrs I have been experiencing post polio syndrome and no real m.s. symptoms. Is this normal? The post polio has really taken a toll on my body and spirit. My right leg Is without hamstring muscles and i ve just had an arthroscopic operation on my left knee. Two days later I was rushed to a close-by hospital with a rapid heartbeat, which was A-Fib and V-tach. I am now on blood thinners and two heart medications. My left knee is still quite painful. What can I look forward to, going forward?
