What Causes Burning And Tingling Sensation In The Knee?

a couple days ago i was stocking up at my job. just walking around and my knee started to get hot. then started to burn on the side and tingle towards the front of my knee. Is this a pull or something more severe. im 35 about 240lbs. 5'7" i have had a torn acl in the same knee but about 15 yrs ago and it was fixed
