Hi! I have been having severe headaches daily and during the day and mostly nocturnal, since the beginning of January. I am a Nurse and have been off work since then. I have been put on muscle relaxants, Tramacet and now Lyrica with what seems as no success in diminishing the severity. I had a CT scan done Monday night with nothing remarkable. I am waiting for MRI that will be done February 14th. Any idea of something else that could help...especially overnight?
