I am suffering from frequent sore throat since last four months , it comes and goes, but by taking antibiotics or prescribed medicines from general physician and gargling with saltwater it gets normal, but after some days it comes back again, I feel slight discomfort and irritation in throat and mouth, my ear also gets hurt from noisy environments, that makes like drum sounds, apart from this, since last three days I am experiencing  blood coming out from mouth once time in day without cough. I consulted an ENT earlier in May. He told me LPR, and pharyngitis, but after 20 days treatment I was feeling good, but after some days irritation and itching in throat came back, or still now it comes and goes. Please tell me, what is this?
