I have been vaping high PG (80/20) for over 2 years, not changed flavors in 5 months... and here just recently started with lower leg itching. I thought my wife had changed laundry soaps, nope. No other changes in my routine (yea I boring). So I took a benadryl and went to bed after a shower. Woke up in the morning, was OK. Went about my day... by lunchtime, it was starting again... and now I am home. Have a few red welts and what not on my legs and also on my stomach... I have never been allergic to anything in my life. From what I read this sounds like a classic PG allergy, weather that or I am allergic to work (which does stress me - the people that is). I don't have much 100%VG around, so this is gonna suck...cause I have to know if PG is the cause. I know most would advise go to a doctor... but I am a little hesitant at this point.
