Oh, blood work is not all that accurate IMO. My doctor says RA blood work is only 70% reliable. I've had osteoarthritis for 30 yrs, and it isn't until it progresses that it shows up(some spurring now shows on Xrays). I have some Heberden's nodes now on my right hand...but it was stiff for a long time before those finally became evident. ( my middle finger is worse than my index or thumb).
Tendons get stiff and shorten with age too...that won't show anywhere on blood work.
Trigger finger may just appear out of the "blue" too. (that involves tendons). Collagen and cushioning molecules often atrophy with age too. Cartilage dessicates and breaks off into the joints... etc etc.
Getting older can be such a bummer!
