question: Hi, I am suffering from upper back and lower back pain.. Initially the pain started some 7 years ago and doctor had prescribed EZACT 120 MG for 2 months... there was no pain when taking the tablets and when stopped it continued. Later took some homeopathy treatment for 2 years and there was no pain after that.. recently from past 1 month the pain started again. All i can note from my earlier diagnosis is HLA-B27 is positive. Please help...
