Sounds like you are on the mend. You can expect issues for literally a couple years and possibly chronic minor issues for years. Alas this all eventually goes away, or we just get so used to it that it stops interfering with our lives. Dry mouth is probably the biggest complaint.
If anything new crops up please don't hesitate to ask about it, either here or with your doctor. The thought of cancer returning will probably leave your head in perhaps twenty years if you're lucky. In the meantime, just remind yourself that it's probably not cancer whatever ailment you may have down the road. Good healing!
