Hi, I Sprained My Ankle First About 5 Years Ago

Hi, I sprained my ankle first about 5 years ago and I have sprained it a lot since then. I had a surgery last year in October to repair my ligaments since they were torn. I just sprained my ankle again while walking down the street 3 days ago. I had tennis shoes on and I didn't step in a hole, it was flat pavement. I have been taking anti-inflammatories for a couple days now and I have also been icing it. Starting about two days ago, my calf has been hurting while I walk and move my ankle, what do you think is going on?
