I have had several symptoms such as sore throat, heavy coughing, weeziness, feel worn out although I haven't been doing much! I woke up this morning, with a small black piece of skin, on the back of my left side of throat! Everytime I swallow I feel it, my throat is more red on the left than the right. I knew I had a simple cold, until I realized different symptoms that didn't match ! I'm very concerned for this, as I'm 19 years old I have never heard or seen this before ! I've booked an appointment with my physician , but she booked an appointment 2 weeks from today! Please help :)
