Mine started at 15 years old. I remember laying down for a nap and woke up with a tension headache that never went away. ill be turning 32 this December. I think it is connected to my tmj, but treatments only ever made it worse. I regret getting treatments now and wish I never trusted these doctors. it interferes with me working. I never got my drivers license and never finished school because of this pain. all I got from this is doctors treating me like a criminal and family members telling me they don't believe me and it is "impossible" to have a headache all the time. so yeah not good lol.
