Lately I began to sing again, and well after over singing I experienced a soreness in my pharynx. Briefly afterwards that I m at present feeling a lump in my throat not literally, but it senses as if somebody got a stone in my pharynx. I recognize this is not cancer, but from over singing, and I would like to know to fix this. I can still raise my voice, my voice I do have to clear once in a while, I can still somewhat sing, but if I raise my voice loud enough it becomes sore.
