I have been taking hydrocodone 5/325 off an on for a couple of years due to slipped disks. My Dr. just prescribed Tramadol 50 for me. I've never taken this med and the hydrocodone sometimes gives me a headache. I also have heart palpitations sometimes when I drink too much caffeine or take 2 or 3 days worth of certain meds, like sinus meds. Is the tramadol the same thing as the hydrocodone? Can it make my heart skip beats like the sinus meds?
