Woke up on tuesday with a very swollen big toe. its red and warm to the touch. cant bend it. possibility of gout or something else?

However, you are young for gout unless you have a medical issues such as kidney problems or other rare medical conditions. I assume you did not injure the toe. You need to be evaluated where labs can be checked including a uric acid level and kidney function. Joint aspiration also may be done
