I'm a male, I am a tenor in choir, and I can go a little higher than alto's but I was messing around today with some songs from various artists such as Mariah Carey, Adele, Carrie Underwood, trying to see how how I can go, and my throat started hurting... I just coughed and the phlegm that came out had blood in it... Should I go to the doctors, or should I just not use my voice for a while?
Is it really that bad?
