I'm getting no help from doctors. Just saw GP doctor and he says there's nothing they can do to help me. I've had a rain MRI and ultrasound on neck all ok. He says there's nothing left they can do. Don't understand why it started in November 2015 with the pulsing,went away for about 6 weeks now it's back. Wakes me up in middle of night and I'm having a hard time falling back to sleep.
