I have been vaping for about a year now and never had a problem. Recently I have had tightness in my throat and it felt like my lymph nodes where slightly swollen. This only happens, to the best of my knowledge when I use my vaporizer. I have quit. Its not worth vaping if I feel this ....ty every time I do. The question is has anyone ever had a similar problem? Do you all think I should go see my doctor?
