Nycgrl, the "headache" is something we had to deal with for quite a while during John's tx. It started during radiation and just wouldn't go away [he never had headaches prior to cancer]. When it got almost unbearable, his Doc put him on an amitryptiline[sp?] patch. He wore it for several days before the adverse reaction began and we had to take it off- BUT the headache was gone and did not come back. Something broke the cycle. Keep pushing the Doc for something else to try for the headache.[John was also on fentanyl, which he could not tolerate, and hydrocodone]Sometimes certain drugs will cause headaches. As to the swallowing issue- he certainly can lose that ability if he doesn't make himself work toward swallowing. It might help to gargle with Lidocaine or some other numbing solution before he tries to swallow. I'm glad he has the peg for nutrition. Learning to swallow again can be a big issue. Hang in there.
