A few weeks ago I had a sore throat accompanied by body aches. No other signs of a cold. My lymph nodes were swollen and my throat hurt very bad when swallowing. I went to the doctor and got antibiotics, it got better within the 2-3 day period. A week later, it came back. I got the same antibiotics and it went away again. Today about a week after healing again, I feel like the swollen type of sore throat is coming back. How can I get rid of this?
