Sometimes i get mild pain (1-3 seconds) around my right forehead, eye, temple, and side of head. can this be related to my tmj?

Possibly: Tmj stands for temporomandibular joint. It is the joint that connects the lower jaw to the base of the skull at two areas or joints. It sometimes refers to conditions that involve this anatomical area that today are referred to as tmd, temporomandibular disorders, a group of various conditions involving the breakdown of any, some or all of the differing components of the tmj.

Possible: Tmj can effect he temporal muscle and causes it be become tight /contracted. As you may know, tight muscle can cause pain. Have you seen a doctor for your problem, you may get help. If its still persist then you want to see an ophthalmologist.

Can be but...: An ailment that may create symptoms like you describe can be TRIGEMINAL NEURALGIA. I am not saying it is TG, and it could be a symptom of TMJ/TMD, but I would be checked soon.

Probably: Probably. Make sure your TMJ problem being treated by TMJ expert. 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.
