ok mine is the 60ml not 40 my last one was 40. i have mixed meds in mine and get a hige dose of fent. and buvippicaine. Mine is placed in the my right side of my stomach. im to little to have it in my back and to much scar tissue. I have had enough pain relief that i am able to work part time and get out of the bed .. before the pump that wasnt even realistic. so im very glad that i had my pump put in 6yrs. and would do it over again. im glad that i did it. wouldnt ever do scs IMO.
