Just from your description of your symptoms, it certainly sounds like RA but it could be something else too. RA can be a vicious disease. Amazing how some have mild RA and get along fine with just OTC meds while others have moderate or severe RA and can barely move even some while using many potent drugs. I feel for you and your Daughter and your pain.
I was first dxd. with Juvenile Diabetes when I was 3 years old. Often when a Person has one autoimmune disease, others can follow.
Not too long after I gave birth to my first child, I started getting bad but intermittent pains and morning stiffness at age 24. I went to a couple of GPs. The first said my pains were only caused by biking too much. Some time later I went to another GP after several other bad attacks. He said he didn't know what type but it was Arthritis of some kind and referred me to a Rheumatologist. I tested positive with a 118. I was dxd. with severe RA after an examination and all the test results came back.
Some People with RA can show a negative RF result but still have RA.
Ra can happen at any age. My male Cousin was dxd. at age 10. My great Aunt was dxd. at age 29. My Dad was dxd. at age 68(many years after me).
If you have RA, I surely hope that you get dxd. soon since aggressive treatment is a necessity.
