I have had several heart attacks and have 2 stents in my heart. i also have stents in both legs. this is due to vascular disease. i have chronic back pain and have been on lortab 10 for a couple of years - 2x a day. they don't seem to help anymore. i also take plavix,asprin,and a number of other meds. any ideas on what i should ask my Dr. for to help with the pain?
