@laurieb63 - Welcome to Connect! I’m glad you can discuss your frustrating symptoms with others who are going through similar illness without a complete diagnosis.
I just want to say that your NP has a good suggestion that you should see a neurologist. You have a hand tremor in addition to sudden severe head pain.
The brain connects with the gastrointestinal tract in many ways.
One that comes to mind is abdominal migraine.
Make your appointment and get a neurological opinion. Also, you don’t have to take new medication unless the doctor is sure it is going to help you.
Please get back to us!
