Hello, I have been diagnosed with Fibromyalgia, Inflammatory Osteoarthritis, possible Sero Negative RA and I also have an extremely bad back (bulged discs, stress fracture, compression fracture, stenosis). A physician at Mayo Clinic started me on generic Arava this past June. This last month or so I have been experiencing burning in my feet, hands, arms, legs and trunk area. Do you think that could be a side effect of the generic Arava, or do you think it is something else? Thank you!
