I have a family member that suffers from chronic, daily, sometimes debilitating headaches. She has had multiple MRIs and has seen a dentist, ENT specialist and neurologist to check for jaw and balance issues, yet no one has been able to diagnose a cause of them. What would be your next course of action? We were referred to a doctor who specializes in headache/migraine, but go figure… he is leaving the practice and his replacement doesn't have any appointments available until April of 2022. Any suggestions or thoughts?
