You should read about TMS by John Sarno (see divided mind). Maybe it can help you too like it helped me. Your symptoms sound a lot like it but ofcourse you need to read it and decide.
Not the original grandfather, but I'm a fellow migraineur. I read Sarno's book, and found it to be unhelpful. From what I remember, the gist of it is that "unresolved emotions" cause a great deal of physical problems in some patients. That's not a theory I'm willing to trust.
