Jaw lock/lactic acid build-up

My jaw locks up periodically on my left side and cracks. I also experience an incredible build-up of lactic acid on the same side when I exhale with force, ie to blow up something inflatable.
Any ideas what causes this?
Is there something I can do at home to correct this, or do I need to see someone?
