I was sick 2 weeks ago and now I have had a cough that wont go away, it's been 4 days. I have used cough syrup, chloraseptic spray, my inhaler, vicks chest rub, and cough drops. It calms down a little when I am drinking water, which I have been doing a lot but I'd have to drink 24/7 for it to stop. I also get some relief when I have a cough drop in my mouth, so I am always sucking on one but its blistering my tongue and I can't sleep with it in. I need relief; my throat feels strained, my head hurts, and I can't sleep from coughing. What should I do?
