I had this problem for several years (soreness in upper area
on the back,
LEFT side of my
head). I also suffered from sudden hair loss
on the crown
of my
head that would not grow back no matter what I tried, and no matter which doctor I visited (dermatologist, neurologist, endocrinologist, etc.). I've had numerous tests done, including an MRI, which all came back normal. I've been put on various painkillers and antibiotics that didn't resolve the pain or soreness.
