About 2 weeks ago I had unprotected anal sex(giver). On the 9th day after my encounter, on a graduation rally, I shouted on the top of my lungs for 2 hours cheering for the graduates. We went drinking and I was able to go home at about 4:30 am. I slept for 4 hours and woke up and went to church. About 2 hours after I had just a mild aching feeling in my throat and I did not mind it. On the 12th day of my encounter I got a runny nose and I still had a very mild sore throat. Very mild because I could eat, swallow, drink water, talk properly. Yesterday I experienced a mild fever(38 degrees Celsius) for about an hour. I only had a high temperature but I did not feel weak, I could eat properly, etc. I took medication after then it went away after an hour. Later that night I drank warm water and coughed up phlegm. Today, I m feeling okay and I only have a wet cough left. My question is is that ARS?
