Hello, I have this persisting stabbing pain in my head. I can move from one side to the other of the head and it can last several days or weeks. I have had an MRI, which revealed nothing. However, from time to time, (especially if I have had a lesion inside my mouth) I get this very anoying and frustating pain. I really do not know what to do. I have been prescribed mussle relaxers, anti inflamatories, and very strong pain relievers, all to no avail.
