Starts with severe pain left side of head/face and progresses to high bp140/90 shakes vomit ft numb stomach pain nausea double vision. No history. Why?

Sounds like. possible variant MIGRAINE.. cluster headches are one variety. TRIGEMINAL NEURALGIA another The double vision/Gi symptoms are a bit "troublesome" At any rate ask your PCP (Primary Care Provider) for a referral to a Neurologist who specializes in HEADACHES....There are multiple medications which deserve a trial however your co-existing medical issues eg Depression MUST be TAKEN into consideration!
