Oh dear. Hate to hear this description that matches my headache situation. It feels like my brain neurons are carrying a low voltage, pulsing electrical charge after I eat anything. Then it’s with me the rest of the day and every day. And I’m very dizzy, more so after I eat. At bedtime I have to use tiny dose of Clonazapam to calm nerve pain in my head and neck. I’m the one who fell on stone floor 8 mos preg but went 20 yrs before I had symptoms.
