i am suffering from low back pain on the left side near back theigh. i have taken pan-d and mayopaz with vitamin B tablets for 4 days 1 tb each a day. i can stand, move and if i take rest on a not so soft bed, i can even sit with folded legs for more than 2 hours. but i have stopped the drug as i had some relief from the severe pain. but now my left arm is showing numbness and still have a low back pain on the left side.
