my thumb is swollen, it happened last night when i ate something cold then went to take a shower my thumb an pointer finger both swelled up tightly and were warm and red and I put alcohol on it, it was swollen when I fell asleep and then I woke up this morning it had gone down but there was still a little tenderness, and then I ate another cold icee a little while ago and now its swollen again not as tight as last night but still tight, but its not my first time eating the lemonade icee, I have had many others this is the first tim it has happened. What does this mean?
