I have had Fibrolyalgia and CFS for quite awhile. Was diagnosed a little over a year ago. A few months ago my fingers became swollen and stiff and I can no longer wear my rings. Fingers become very painful and swollen during the night. I always wake up unable to curl my fingers to make a fist. As the day goes on I am never as sore or stiff, but fingers are still very swollen. I recently had a test for arthritis and it came back negative. My G. P. said it was due to the fluid around finger joints, and to soak my hands first in ice water and then very hot water several times. This didn't help at all. HELP It's a mystery!!!!!!!!!!!!
