Hi Hippi,
This is lupus, so no question is a wierd question. I get headaches also when I'm exposed to second-hand smoke. Not just from cigarrettes, either; I can't be anywhere near campfires or grills. I hate having to stay away from the campfires, I love them so, but I get migraines being around them. Like you, this started after my diagnosis, but not until about a year ago. I have yet to ask my doctor why this is happening. I need to remember to write that question down.
