I have had symptoms of PA for over a year and was bounced between doctors before recent diagnoses. I am frustrated with my internist and neurogolist. Neither will allow more than one shot a week and the neurologist wants to do an MRI to "fish" for causes of my memory loss and discounts the new neuropathy symptoms in my legs as been related to PA. I live in a rural Missouri (USA) area and I think my doctors are inexperienced with PA and don't want to step on each other's toes. Could someone from the St. Louis support area give me the name of a doctor who specializes in PA? My insurance is COX Health a reference for someone in Springfield MO area would be amazing helpful.
