Hello. Dr. I have been experiencing the following symptoms for sometime now. Feeling of pressure in my head, Pulse, electric shocks sometimes, faint,headache, feeling of dizziness when walk at least 300-400meters. when it happens, i feel very week in my body and feeling like iam going to die. Have had a MRI test and blood pressure control monitoring test for one day. Both were done almost a year ago. The symptoms are getting worse. Makes me very frustrating. I am just 33 years Old. Can you please advice me what to do?. Have been running from doctors to doctor getting not better. What could be the course of these symptons Koby
