Can PMR come on more gradually?

Three to four years ago I had a lot of stiffness on,ly when riding in a car even for short distances. No pain but just weakness in kegs and stiffness after sitting. I went from walking 4 miles a day to not being able to walk much at all. Attributed it to afib which was permanent, the. This past December I worked out in 35 degrees all day…..overly cold and tired. Them the symptoms came in like everyone talks about. I could barely move…..searing burning pain and stiffness everywhere. Doctor gave me two ten day bursts of prednisone which helped immediately. I still have stiffness and extreme fatigue on many days. I finally got into a rheumatologist who said he couldn’t help me because my blood work didn’t show but a tiny bit of inflammation.so I take Tylenol and sleep two hours nearly every day. My primary doctor said I was a classic example of PMR but she did not take blood work when I was having flare.rheumatologist said he could not diagnose PMR without inflammatory markers. I can put up with stiffness but fatigue is so hard to deal with. Any ideas on this mess?
