+DeeM cSweeney - No, negative things cannot happen whilst listening to this. - except the possibility if you suffer with epilepsy - as the 'pulsing sounds' may trigger seizures. In regards to the Shingles coming forth.... this is the beginning of healing. Shingles start from within, once they start coming out (pain and all) this is the end process of the virus - and the worst feeling I might add!!!) So, in some ways, it may have done you a favor coming out so quickly. Unfortunately, I think at this stage of the virus - no medication helps... I'm no medico, however, I've experienced Shingles myself a number of times when I was stressed years ago... I hope the pain will go for you soon.
