Since Old Toby bit me last Friday, I have had a small canker sore (small white swollen spot the size of a taste bud) on the tip of my tongue. I've had these pop up now and again my entire life and while a mild irritation, I know what foods and drinks to avoid while it's healing. However I'm not entirely sure how it would be affected by pipe smoke and if I should wait till it heals up to smoke again. Has anyone had experience with this?
