One thing that you may want to monitor and speak with your dr, when I first went on pain meds i did ok,,but thru multiple surgerys[ball player] in the last 6 years,,the liver gets sensitive to all of our meds,and i started to have early adverse effects,,,Pain meds when the liver is weak causes respirtory problems and the heart causes this as well,,,also an allergic reaction can do this as well,,but from my dr's point of view,,after years of useing meds,,our livers get so sensitive that even a smaller amout causes adverse effects,,and also that pain meds weaken the heart and are hard on the heart,,thats why alot of elderly patients to whom i know who are in pain cannot use them,,but a weak heart and liver , run hand in hand,,plus all the other meds that we have to take does indeed overload the liver and heart,,,I sincerly hope that you find what your looking for and get pain relief,,This may not even apply to you,,but all info and ideas are worth investigating,,goodluck to you,,,,,,,,,,
