interesting... because i am having severe pains in my lower back. It started in my lower back and spreaded to my hips. I went to er twice and they say i spranged my back. I know that isn't the case. I am not a doctor but i do believe I have arthritis. M yaunts and grandmother all had replacements by the age of 35. Go figure..... I am 33. I am walking with a can right now and popping percocets like no tomorrow. I need to go see a speciallists.
With a family member with an autoimmune form of arthritis and your symptoms, it is definitely possible something is going on but it may not be RA. What other blood tests did your doctor run? Do you have the results? Did they take xrays of the joints in which you are having pain? What about an MRI? Is your doctor helping you with your pain?
