I experienced jaw pain for months. I kept thinking that my TMJ was acting up. Went to different dentists and doctors and not one of them ever thought it was anything else than TMJ. Then, my head started to hurt unlike any headache I ever experienced Finally, after suffering for so long, I demanded a complete blood panel. Lo and behold, that is when all my ailments were pieced together and GCA came up.
Please do not wait. Time is of an essence when it comes to GCA. My best to you.
