One of my knees burn a lot after I walk and climp up n down the stairs a lot. Why? What happened to my knee?

Answer:
you might have an inflammation around the joint,how old are you could it be arthritis?best go see your doctor,if not then take some anti-inflammatory like ibuprofen etc.keep your leg straight out not folded when sitting and make sure you have good shoes!i have bad knees from horseback riding thats what i do.also i have a pair of tennis shoes that are just for in the house no bare feet my doctor said.this will also help your heels and ankles.
