I'm female. I've never smoked, done drugs or anything like that. Several months ago, I had a sore throat from screaming too much that turned into a nasal drip. Went to doctor, he gave me medicine, and I recovered, but my cough remained. I got sick several more times but my cough never went away. It's a mucus cough, and I have to clear my throat regularly or it'll go hoarse. I puke regularly (PMS) and I cough out mucus sometimes. My doctor thinks it's asthma, but the inhalers are so expensive that I don't want to pay for it if it won't work. My voice has weakened a lot, and simple yelling can cause me to be very hoarse. Should I go back to my doctor and see if it's asthma or what else could be the cause?
