Tmd dx. ear pain, sore muscle down front of neck, popping jaw. can this cause lower jaw pain next to molars under tongue? cold fluid causes ear pain?

Yes, it can: Myofascial pain syndrome, is a regional muscle disorder that is one of the most common causes of persistent pain in the head, face and neck regions. A myofascial pain is defined as a localized deep tenderness in a taut band of skeletal muscle, tendon or ligament that has the ability to refer pain to another region known as a zone of reference (i.e., area of pain complaint). See orofacial pain doc

Pain and dysfunction: If the tmj/tmd issues last for awhile, some symptoms can affect the ear (s) in many ways. You may develop ringing in the ears; earaches, popping-grating-clicking that is heard constantly in the ears; roaring muffled sounds; hearing loss; on and on. It is better to see an ENT first if you have ear symptoms to rule out it being the ears as the source of the problem.

Dr Malerman and another doctor agreed

Yes, but: Yes, but with extensive symptoms like yours, I'd see an ENT doc to rule out other medical problems. 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.
