back pain
"I had a horrible experience with this medicine, took only 100 mg once in the morning for a severe low back pain and could hardly function. I became so nauseous, vomiting, disoriented, dizzy, my head was clouded, all I could do was try to find a place to lie down. I guess this is what they call high intolerance/allergy to certain medicines. If you know you have a sensitivity, be very careful. It helped my pain some but made my day absolutely miserable."
