Sports injuries( ankle, knee)

Patient: I have been playing basketball for a long time now, street as well as professional, and often had minor and some slightly major knee, thigh and ankle injuries in both legs but i never visited any doctor just some brufen cream, icing and back to court again, but now whenever i play basketball or even jump twice my ankles and shins hurt alot specially in the winters, my knees hurt if kept bent for more than a minute, i cover it up with a warm bandage for a few days and then i am good again, when i stretch my legs i feel something setting and dislocating in knees, ankles and shins. some times i cant put weight on my ankle at all. should i visit a doctor or just put on the bandage for a few days again and let it go?
