I did some research on PG today, and found that in a small portion of the population, it can cause dermatitis. I've been vaping since November and the last month my legs have become increasingly itchy. I thought I was allergic to my dog or something, than I thought maybe it had something to do with my e-cig. I'm pretty sure that I am mildly allergic to PG. Has anyone else had similar symptoms? Would switching to VG help?
