The blood tests that indicate uric acid (urea) came back normal but the cherry juice sounds good anyway. I read up on the Polymyalgia Rheumatica and it sounds like exactly what I have in spite of my earlier Lyme suspicions.
This pain and stiffness is not just aggravating, it is downright debilitating. Can hardly get out of bed in the morning and it hurts bad to get in and out of a vehicle and to sit and drive also. Hurts to even turn a steering wheel. After sitting for just a short while it is tough to even get up.

Doug, not making fun of your situation (far from it), but if you wanna shoot a couple deer and can't sit in a stand, point your truck west 2 hours.
Got a a few windows to watch and a warm woodstove.
90% chance you can shoot a buck and doe and stay comfy while doing it.
I despise illnesses but more so when they can't figger it out.

I feel bad for you. Seriously if you need help with anything let me know. I hope you feel better soon. My guess would have been a tick disease.

Tick Bourne diseases are notorious for false negatives. I had similar symptoms for 4 years. I saw several doctors over that period and had at least 6 tick panels run . Then I got real sick body temperature was swinging from 102 to 96.8 , hyves, severe muscle and joint pain . My current doctor ran another tick panel and started me on doxycycline. I was better immediately. The tick panel she ran was negative but when she checked the results she went through my permanent medical records and found a test another doctor had run 18 months prior that was positive for rocky mountain spotted tick fever. The previous doctor had mis read the test results and told me I had no tick Bourne illness. After 6 weeks of antibiotics symptoms I'd had for four years disappeared. Athletes foot , aches and pains blurry vision a kind of cognitive skip all gone . I talked her into extending my script for doxy for another 3 months because I had it so long I felt it was in my brain and it takes more than 6 weeks to penetrate the blood nerve boundary. She agreed that everything my friend had told me about his battle of 10 years with chronic lyme was accurate and I was right to be concerned about a deep infection or a secondary infection that wasn't showing up on test .
