My husband has very stiff joints almost everywhere. Wrists, fingers, arms, thighs...He only feels tightness, without any pain though. We were sent to a hand specialist at first (since the stiffness originally started with his right wrist being swollen and inflamed). MRI shows that there is fluid where tightness is, but cartilage looks good. The doctor said he has not seen anything like this (stiffness without pain). Rheumatologist suggests that it may be Ankylosing spondylitis, but this should accompanied with pain, while my husband does not feel any. The rheumatologist said he may have a very high pain tolerance, which is not true. He is very sensitive especially with pain. He is now getting less and less flexible each day unfortunately. Has anyone seen/ experienced anything similar? Any insight will be much appreciated.
