Hi, Im A 48 Year Old Very Overweight Out Of

Hi, im a 48 year old very overweight out of shape male, i currently within the last week have been dealing with some form of edema in my left ankle leg calf, swollen redish shiny skin and its been hot to the touch very uncomfortable. Ive had a few flare ups in the past but they would normal go away after about 3 to 5 days. Its been about about week now and today i started leaking yellow fluid out of my leg. What is happening.
