Yep, when I'm in a flare, I have the same thing happen to me. My hands are always the worst, but it gets my feet and legs too. Even with long sleeves, long pants, sunblock, hat, sunglasses, the whole thing, I can still get the effects of the sun. Unfortunately, the only thing I found that helps is to totally stay out of the sun on those days. I stay in the house and keep myself distracted as much as I can. I have no idea why it happens, because it seems like we do everything right to protect ourselves. Then again, so much with lupus makes no sense! And when I'm not in a flare, I can be out running errands with no problem, as long as I have sunblock, hat, etc.
