It does sound like gout according to what you're telling me and the chronic evolution. The skin lesions could be the crystals breaking through the skin. Either way, you need to have a it checked to confirm the diagnosis. Alcoho and fructose is going to be the biggest factor if it is gout, but it doesn't necessarily have to be uric acid that is the culprit, it could also be oxalates. Do you have a history of eating high oxalate foods over the years like cacao, beans, spinach, almonds, cashews, peanuts, sweet potatoes, beets, green smoothies, dried fruits, chia, kiwi, grains, etc? I recommend reading Toxic Superfoods by Sally Norton if you want to learn more about oxalates.
