I’ve had migraines for years, variants along with traditional headache, but usually my head pain isn’t truly severe. Other odd symptoms wax and wane most days of the week- days of feeling washed out, foggy head, noise sensitivity, stiff neck, and shortness of breath. My heart rate can become lowered or higher too. All tests are perfect-I’m very healthy otherwise. Read elsewhere about something called migraine syndrome and wondered if it’s a currently recognized issue…it sure feels like it!
