a dent appeared in my head this week, then another, and another, and there is a strange migraine, like tightening on my crown, of skull, and slight buring in the depressed areas, and it goes to the core, behind my cheek, and eye, .... I have a traumatic brain injury, from 70 impacts, and trigeminal neuralgia, from an incident, 20 years ago.. that MRIs showed cerbral thrombosis with Infrac. ...but, this new thing with dents, and that pain, is different from my chronic pain..
