It's very likely that your problems are related to PPS; however, most of the younger doctors don't know anything about it. However, we're fortunate in Birmingham (AL) to have one who does. Is there a Post Polio Support Group in your area? There are also numerous web sites which could give you info on this. Just put in keyword "postpolio." We have about 30 in our group in Birmingham and learn a lot from each other as well as the professionals whom we have speak at our meetings.
