Having an aching pain in my upper back between shoulder blades and down the side of the spine to bra line. Came on the day after an 8 hour car ride. Hurts when I cough and sneeze but can take deep breaths in. Doctor thought it was just muscle related and gave me muscle relaxer & anti-inflammatory. Neither seems to work. This all started between shoulder blades and on left side area then went just to the middle and now on the right side while still hurting in the middle. Could not lie on either side at first...can now. Advil seems to work better than those two meds. I have Lupus and was wondering if any of this could be related to that.
