I actually had to be wheeled in to my doctor's Day Call (its like the Urgent Care practice in the very big Internal Medicone clinic I go to) because of what Id thought were acute injuries due to overdoing my hiking. Xrays were mostly normal. To my IM Dr, who ordered sed rate and CRP - normal. A month later I saw an orthopedist/sports medicine dr. He thought it was rheumatoid as did my IM dr. Ordered a repeat on Sed rate and CRP. Told me to prepare to meet a rheumatologist in my future. Got back to my IM Dr and my labs were now abnormal, so hallelujah- referral to rheumatologist who diagnosed PMR.
I usually described my pain as "aching", it is a dull pain that varies considerably in intensity.
