I have insane foot and knee clickin/popping and light pain, plantar fasciitis?

Foot / knee clicking: There are several reasons that this can be. There is no way of knowing from this exchange but you do not have to remain in the dark or put up with it. Most of the time it is related to inflimation, poor alignment, sprain/strain or even a partial tendon tear. Go see your podiatrist or orthopedic doctor and in the meantime avoid activities that hurt or bother the areas. Good luck.
