I have searched the forum on this particular subject, and, while there are some discussions about symptoms and solutions, I was unable to find a situation like what happened to my wife and her friend. My wife had already been vaping a few years and recently switched to organic VG because of small skin reactions. Her friend just started vaping. Both had boils developing on the bodies. After numerous futile remedies, I remembered that my wife had mild allergic reactions to anything coconut. Her friend too. I realized, after calling many ejuice manufacturers that almost all Vegetable Glycerin is based on coconut oil. (This fact can be found in the forum.) I did find a manufacturer (Kind e-juice) that made Organic VG based on rapeseed (canola) oil. After vaping for many months, neither has had another episode of boils. If anyone has such a reaction, knowing you are allergic to coconut, call the manufacturer. I'm sure there is more than just one that does not used coconut oil-based VG.
