I became very photosensitive in late December early January: grey days, tungsten & hallogen lights. Particular red shape on face with leg & backache. It has become less instant. I've been taking hydroxychloroquine since mid May. The heatwave was a disatster requiring antihistimes & short steroid course, skin not recovered yet. I cover my face [scraves and/or uv protection coolmax "Buffs"], long sleeves, trousers & wrapround anti mist UV protect glasses [affects my eyse too]. Heat & sun combination the worst.
