I have a constant poping in my ears. have felt very uncoordinated and have been getting sharp very painful head aches with it.

Let me explain: A change in air pressure on both sides of the eardrum is the primary cause of popping noise in the ear. When the eustachian tube becomes blocked, air pressure builds until the middle-ear air pressure cannot fully equalize. Air pressure differences typically occur when flying or driving at high altitudes. Allergies ruptured or perforated ear drum sinus infection ménière's disease ear infections.
