Recently, I noticed a small irritation on the side of my tongue. It really didn't hurt much, but then that side of my tongue started to swell. Just the half with the irritation swelled. It got so big it impaired my speech and I had trouble eating. I was afraid it might block my airway. It lasted for around 4 to 5 hours. Has this happened to anyone else? Is there an over-the-counter pill that would reduce the swelling? Any thoughts? Thank You.
