I've noticed when i go to sleep i wake up and my ear is clogged been having pressure in head and sharp pain in neck what could this be?

TMJ vs ear: Could be a TMJ problem, or an ear problem (like wax buildup). See your ENT doc to check the ear. If negative, see TMJ specialist. Any dentist can be a TMJ expert with the proper training and experience. Most commonly, oral surgeons, prosthodontists, and orofacial pain specialists. Ask your MD, your dentist and your dental society for referrals.
