Would joint pain mean lactic acid buildup?

So for 1 plus year I have been having joint pain in my ankles, knees, and sometime wrist. It happens randomly and the pain is inside the bon. I was wondering if it might be a buildup of lactic acid since I always have nasal problems making me breath with my mouth which doesn't give enough oxygen. I noticed that I usually have pain when I either have a congested or runny nose. Would this joint pain be caused because of the build up of lactic acid.
