Hi Eliza, sorry to hear about your vocal issues. My guess would be that it’s mostly e-cigarettes causing your problems (or / and allergies?). The vapour produced during vaping is highly irritating and it is inhaled passed the vocal cords, which causes inflammation of the lining of your cords and throat. Your best bet will be to speak to an ENT specialist, but meanwhile, perhaps you could also try stopping e-cigs for a week or so to see if this helps? Best wishes 🙂
