Over the last few months my husbands tongue swells up during the night and is huge in the morning. It can take all day to go back to normal. I am sure it's not an allergic reaction to any thing as he has eaten nothing different. He has always snored. I am concerned as he had a cancer spot taken off his face just under the eye about 3 years ago and was wondering if he has more cancer. Can you help please? I'm sorry. I have no money to pay you.
