Joint Pain, swollen and redness of joints

Since 17 years old the cartialidge around my rib cage has been on and off inflamed. At 22 this problem spread all over my body, including fatigue. My doctor was certain it was RA. Now 23, this sickness continues to get worse making life almost impossible to live and some days I have to be in bed most of the day because of some activity I did prior. I am on an NSAID, which has stopped helping me as much as it once did. I cannot do any activity with out feeling Pain, being swollen, and feeling tired! I was shocked when my blood results came back and my sed rate was normal. This left me feeling very confused. I can see the redness, see my joints swollen, and I can feel the pain. It is in my hands, wrists, knees, ankles, rib cage, spine and hips. This pain is something I feel every single day, and usually about 4 joints a day will hurt but they are somewhere different with each day.
Also, with this usually when I feel fatigue, my eyes get hot and sometimes burn, my doctor couldn't help me with that one. I am wondering if somehow my immune system is invloved when I feel that way, when fatigued, I am often imobalized. My question is, since my sed rate came back normal, should I rule out arthirtis altogether? Some family members are insistent that it is fybro.
