Nink thanks for responding to my question. I have been taking 10/500 hydrocodone for about a year...Ihave to take it w/flexeril or I do not get the pain relief necessary to refrain from the fetal position!! Thank heaven I found out I was seriously allergic to morphine but what next? The level of pain due to the SS and the FMS pain problem probably does't help...what is next? I have, like everyone else on this board probably, MitralValveProlapse and PVCs. I take a beta blocker to make my heart work more efficiently....avoiding tachycardia and low,low b/p. I have been wondering what surgery would do to that situation. Thanks. CctusLil'
