I did not know until I read your post that heat could be the cause of migraines. It doesn’t happen all the time. However, I have noticed that if I get over-heated I get this insane headache, I get very sick and the pain is so intense I can do nothing. I take OTC pain medication and go to bed. It depends on how fast I can get medication in me, get cooled down and lay down as to how long the pain stays. I will talk to my healthcare provider about this now that I know this may be what is happening.
