Are you talking muscle pain? I use flexeril daily for neck muscle pain. You should have your doctor look at your arm - especially if its just one arm hurting as I don't know of lupus just attacking one arm.
Sorry you are feeling so crappy! Lupus can cause some of the symptoms you are feeling. Have you asked your PCP to run a ANA test or have you been evaluated by a rheumatologist? You should talk with your primary care doctor and just ask him/her if lupus would be a possibility as they would know your condition best.
I've had more trouble with lab work over the years - even at the Cleveland Clinic - where on the same blood sample there would be inconsistencies like the above problem....sigh....I use to believe in test results, but not so much anymore.
I'm staring at recent lab results trying to figure out the relationship between ds-DNA and histone AB. I know histone AB are seen in drug induced lupus but is it possible to have high (376) ds-DNA with drug induced lupus? Or is possible to have high histone AB with SLE? And how in the heck is it possible to have a normal ANA on the same blood test?? I'm beginning to think none of my lab work can be trusted... Sigh...
Any light you can shed on their relationship would be much appreciated!!
