... arthritis. I have pain in my elbows where I cant bend them at night, they are so stiff. I have a hard time laying on my sides to sleep. The rheumatologist told me that it is fibro; but i had mri's done and they say arthritis?? I also have aching legs at night. Is that fibro in my elbows and wrist and knees ect?? The dr told me that fibro has pressure points. I believe that he doesnt tell me the truth about arthritis because I am on medical asst. Other drs told me arthritis. What is the truth??
