I began Isoniazid 10 days ago for LTBI. Have been on Cimzia for Crohns for 3 years with no problems until 3 positive tb tests, both types, skin and blood. Have had some pretty severe low back pains (level 8) off and on as well as very spacey/light headed. Now gums and roof of mouth are inflamed and tender. My upper teeth hurt and nothing seems to help, having tried warm salt water, cider vinegar rinse, and Sensadyne. Went to DDS within last month with a good checkup and cleaning. Can't take Aleve, Ibuprofen, or Tylenol because of Isoniazid. Can't take aspirin because of Pentasa for Crohns. Please advise.
