Poor you Paul. Sounds like you have really been through the mill. Great to hear you are currently ned and lets hope you will never have to go through this again. Still waiting on the biopsy results. The neck ultrasound i just procedure so my worry was unfounded but very nervous to get mouth biopsy results. Just wrote a post about nicotine lozenges. I used them for two whole years and they brought me out in canker sores all the time which went away thankfully but now im thinking oh my could they be related to what im going through now with this ulcer. I have been run down so perhaps a reason for ulcer but otherwise, i never get ulcers really. Also its an odd location, right in floor of mouth under tongue.
