Thanks to all for the info and support.

The apthous ulcer now of 2 months has gone down a bit to the size of a pencil eraser. I had an appt. with my new PCP last week but we talked about MS for most of the appt. WHen seated about 4 feet from each other I pulled my tongue out and over so she could see. She didn't get out of her chair but said if it isn't going down in 4 weeks we can do the ENT.

Since it is going down I am assuming it can't be cancer. My parotid gland issue has never fully resolved and it swells every night.

I'm not sure what to think. My 30 years of smoking made this a terrifying possibility.

Should I just relax about this?
