Getting bad headaches for months at top of head with pressure feeling, my head feels sore to touch, like my hair is sore, what could it be?serious?

Might be TMJ: There are many things you could have. Sometimes significant clenching of your teeth can cause muscle spasms. The temporalis muscles go along side your head and under your hair. Try Ibuprofen every six hours, try a cold pack along the sore part of your head. Eat a soft diet, be aware if you might be clenching your teeth. If so, see a TMJ or bite dentist for help to break the spasms.

Possible tmj: Could be tension headaches associated tmj. Recommend you consult your dentist.

Headaches - hair: A headache on the top of the head and where the hair is painful is commonly a muscular contraction headache and must be dealt with from a neuromuscular orientation. The dental bite must be set properly (vertical dimension mostly) and the trigger points in the splenious capitus and scm muscles must be treated properly. I like travell trigger point technique as it has helped patients 30 years.
