About six years ago, my doctor gave me some samples of a drug to treat pain from an injury. I took it for a few days and then woke up one morning with a big red blister on my tongue. I’d never had anything like it before, and I wondered if the pills might be to blame. They weren’t helping much anyway, so I quit taking them. The blister went away. I mentioned it the next time I saw the doctor, but he said it must have been a coincidence.
