My initial occurrence of PMR was Sept. 2019 and it lingered in various intensities through mid-July 2020. It remained undiagnosed that entire time. In mid-July on my 70th BD I was sent to ER (Happy Birthday) and was diagnosed with Pericarditis. Stayed at Mayo for 3 days. But on day one the Doctors prescribed for me Colchicine & 40 mg Prednisone. Well that immediately addressed the pain from the Pericarditis as well as completely & simultaneously eliminated all body and muscle stiffness from PMR!
