Hi, I have had stiffness in my legs when I wake up in the morning, when I sit for a period of time. Bending down to tie my shoelaces is becoming difficult They did an examination and some blood test, said I have RA.. But I am not totally convinced, because some of my other blood tests are normal. Any suggestions

Summarized question: Is rheumatoid arthritis the right diagnosis for stiffness in the legs?
