Hi Dick, I can't be of much help with the pain but do drink lots of water. Most of my pain was caused from radiation burn on my skin. As for the smoking I swear to you that I tried EVERYTHING known to man from patches, pills, hypnotism etc etc etc. What finally worked for me was setting my mind to quitting and littering (beat me) the highway all the the way home from a doctors appointment with my LAST pack of smokes. Yep, I went cold turkey and found it very easy. The trick is you have to have the WANT more than you want the smoke.
