So, for the last several years, I have noticed when working in the garage - grinding, welding, etc - I am the most prone to migraines. I got one Friday and again yesterday. Both times welding on my boy's car. Got me thinking....could my auto darkening helmet (cheaper one I got my boy so he could help but it recharges the battery from the UV light from the arc vs watch batteries like my good one) not be reacting fast enough and it it the flashes that are causing them? random thought
