It did, however, trigger a bunch of other stuff, including these weird red rashes on
and forearms that come and go. Mainly they occur at night and disappear after I sleep and wake up. I've had them since last August, through the winter, too (so it doesn't seem to be related to heat, at least not to heat only).
This year I've traveled twice--once to Mexico, once to China--and both times the rash has been out of control.
