Same. I have had a few types of headache issues most of my life and no one believed the pain was that bad because I don’t express it the way people expect when in severe pain. So, I always thought I had a low tolerance until a doctor freaked out at some severe tibial stress fractures that I was still being asked to run on them. And it took faking a painful yell when the doctor was manipulating it in the first visit to get the bone scan ordered to get to that freak out. I just don’t uncontrollably verbalize severe pain or fully shut down or things like that like neurotypicals.
