Silent Migraine

Today I had a very scary experience. Have you ever heard of a "silent migraine?"

This afternoon while washing the porch I experience some bizarre visual symptoms. I looked up, saw halos and became very dizzy. My visual field went nuts with blurry zig-zags that flashed. I was certain I was having a stroke or some horrible sort of brain tumour. I and called E.  I think all the stress got to me.  I've edited down some web MD stuff:

The Symptoms of Silent Migraine

The symptoms of silent migraine include any of the typical signs and symptoms of a migraine -- but without the pain.
Physical symptoms include:

• nausea
• vomiting
• loss of appetite
• thirst
• chills
• fatigue

Emotional and mental symptoms include:

• confusion
• irritability

Aura symptoms include:

• wavy or jagged lines
• flashing lights
• dots or spots in your vision
• blind spots
• tunnel vision

An American Migraine Study involved 30,000 people with migraines. Nine out of every 10 said they couldn't work or function normally when they had migraines. More than half said they experienced symptoms severe enough to need bed rest. Even without the pain of migraine, the other symptoms can be temporarily disturbing and can disrupt your normal day.
