I have been battling this for 3 days now and I'm max irritated ! I went to the docs office thursday and they said I have sinususitis nd nd I got clariten it clearned my nasal but I am still coughing when I breath

its irritating he gave me antibiotics just incase I didn't feel better is this post nasl drip .. Or what .. Sometimes I do get pain in my ears and pain in my uper jaws

... I got tested for HIV they said it was negative but 2 days after my result came back I got this lil runny and stuffy nose with a heavy temple headache. And then like I said I went to the urgent care Thursday and he said its allegies well now my throat burns like a heart burn unless mucus is back there what's wrong with me help
Help guys please
