"i have chronic lower lumbar pain from a bone disorder that affects mostly my lower back. pain can be excruciating at times. i was taking the tramadol 50 mg tablets for a few years they helped some but i had to take more and more of them. my doctor put me on the tramadol er tablets so i take 1 tablet a day. it is great. with one 300 mg tablet a day i can function fine. it gives great pain relief."
