Over Christmas I developed a very nasty chesty cough but with no mucus and ever since it hasn't really gone away. Its not so much of a chesty cough now but I keep getting this kinda sharp pain in my throat like its being jabbed with a pin, this is causing me to cough quite a lot with mucus to the point where I'm almost throwing up. I have no idea what it could be so any suggestions would be good, I don't know if my age would help but I'm 16 anyway thank you.
