I've taken vicadin and perco's on and off...(mostly on..) for four or five years. This last time, after insurance making me change dr.'s, she proscribed me Norco. I've had the most terrible heart pains ever. I don't understand what the difference is, but I really don't like it, and am thinking about just stopping them. If asked, will the pharmacy, or dr. give you a choice? Is there a different 'kind', or brand of norco that can be changed too? I guess in general my question is also, do pain meds make your heart deficient? Or somehow just not work as well? I'm quite worried, at this point I went back to taking my higher dose of perc's, I have on hand, just because the Norco scares me. Any help will be apprciate it, I think it's paranoia, but I think about things like "keeling over dead" and my kids finding me. I'm 33, and when taking the narco, six in all, a day, two early morning, to afternoon, two night. When taking the perc's, one and a half, three times a day. Is this a ton? I'm I destroying my body? I just don't know how to NOT using them, because my pain is incredible, even at this amount I take. Thanks so much for taking the time to read my questions, truly hope to hear from someone having the same problems.
