I am new to vaping about 2 weeks and was really 'getting the hang' of it when about 5 days ago I was awakened with blister-like hives in various areas of my body. I at first thought a flea or spider befriended me under the bed clothes and just used Cortisone and Benedryl gel to calm the horrible burning. I continued to get the hives and never gave a thought to vaping for about 2 more days 'DAH' I quit the vaping now 4 days -some of the blisters have healed but I am still getting 1 or 2 a day -- I have not slept a whole night in a week with the burning itch and swelling and ended up seeing my Dr today who perscribed Prednisone for 3 days .I am holding off taking it in hopes it will resolve and flushing my system with extra fluids . I did drink plenty of h2o while vaping . I used a vision spinner -iclear - tobacco and blackberry e juices. I am now soooo disappointed . Please I hope not to discourage any new vaper'er but it seems like something in the e-juice had an accumulative effect as I had no symptoms the first week.
