The docs were convinced I had it but after a right heart catherization they said my lungs were fine.
Initial symptoms of PM are proximal muscle weakness affecting the hip and should girdle. Getting up from chairs, climbing stairs, raising your arms over your head are the most common symptoms. You can also have swelling, redness, muscle pain and swallowing problems but every case is a little different.
