I had a terrible case of heartburn awhile ago. Thought I was having a heart attack, or an allergic reaction to chemo, it was scarry. What happens with chemo is it really messes with the intestines so then gas backs up toward the chest. It messes with the whole digestive system. I am glad you take care of your chewing. I must always do that also. I have always had a habit of eating too fast. And maybe chewing gum would help Leslie. I also find that a mint helps.
The tightning they refer to, occurs during infusion and last up to a day after and then is supposed to resolve. Does she have mouth sores to go along with her hand and foot syndrome? They might affect sensation in the throat. Of course just having cancer, a recurrance, hand and foot sores what normal person wouldn't have a tightning of the throat. If I had the feeling I might try using one of my xanax's to see if it worked, at least I would sleep My heart goes out to Leslie, I have only had anemia and a skin rash 5 days after treatment from the doxil. Sorry Star
