My mom has gone to the ER three times over a really bad headache, whats happening?

She needs to go to a regular doctor and get tested, ER's don't spend the time to get to the bottom of problems. They just patch you up and send you home if you are not bleeding and still breathing. If her regular doc doesn't have an answer he will refer her to a neurologist. Plus they are expensive.

I don't think they are going to find anything again for headaches are caused by tight neck muscles. The muscles go to the top of the head where they connect to muscles going around the head. When the neck muscles get tight they pull the head muscles into pain and that's the headache. Tests and scans don't show the tight muscles so they go undiagnosed. When your mom was at church and singing she ended up tightening up her neck muscles even more to cause the headache to set in. To get rid of the headaches she has to free up her neck muscles so they can't pull the head muscles into pain any longer and here's how to free them up for her relief: Neck: Put your hands alongside your head so your thumbs are on the front of the muscle under your ear and your fingers are on the back of the muscle, behind your neck. Squeeze your thumb and fingers together and hold. Relax your body. When your fingers and thumb touch, about two minutes, slowly lower your head as far as you can, release the pressure but hold your neck extended (lowered) for another 30 seconds For best results relax the body first by taking a deep breath and exhaling then remain this relaxed. She may have to repeat this a time or two if the muscles are really tight. good luck.
