Gout is a very real possibility. Usually, gout effects men over the age of 30. Most importantly, infection should be ruled-out. The best way to determine why a joint is swollen and painful is to look at the joint fluid. Urate cystals confirm the diagnosis of gout. Calcium crystals are found in "pseudogout". Pus means you have an infection.

Blood tests can point to important clues with white blood cell counts, uric acid levels, and blood cultures (if neccessary). X-rays probably won't be helpful in this early stage (unless you recently dropped a hammer on your toe). See your doctor to sort things out.

By the way, some occupations (like carpet installers) are more likely to develop big toe problems. A steel toe boot will prevent that problem.
