Hello, I have searched here but can't find answers. One of my oral cancer friends has recently had a permanent peg installed two years after treatment for BoT cancer treated by chemoradiation. He can eat only a very small amount by mouth and is very thin. The big problem is that he is suffering frequent, sometimes constant nausea and no-one seems able to figure out why. He IS putting on weight so doesn't want it uninstalled but nausea (even after meds for it) is a terrible thing to have almost all the time.
