Hello, Only recently I learned about PPS. When I was 12 or 13 a summer clinic claimed I had bulbar polio 3 or 4 months prior. they said I was lucky to be alive because only 3% survived. But I thought I was lucky to have that type and not have paralyzed legs. At that age running around outside was more real than death. In 2005 was diagnosed with spinal stenosis. Is there a relationship? And reading about PPS online explains why for the past 20 or 30 years (maybe more) (I am now almost 80, brain and limbs working) i clear my throat constantly, cough, sometimes choke and then vomit. I always keep cold water handy, seems to help. I have NEVER told any doctor about it thinking of it like mumps or measles. Am I on the right track about spinal stenosis, and all this swallowing and choking problem? many thanks for your input. carolina
