Suggest Treatment For Swollen Ankles

I am 63 male 1.73m high, no medical history, never operated, otherwise good health. Recently I get my ankles swollen, both legs, the part of my leg that articulates with my feet and that stay days after days, I try to lay down and place my legs higher to rest and circulate often, take hot baths, but nothing so far changed, also have small varicose veins on both my legs and some of it over the areas that swell, I thought that may have to do with food and I am looking to understand what is Gout. Some advise will be appreciated, Thanking You, Bye, E.
