About 3 weeks ago I had protected anal sex and unprotected oral sex (receptive) with CSW in Southeast Asia. About 2 Weeks after this encounter I devolped a Swollen node on the left side of my neck only, that was quite painful and it lasted about 4 days it went away after I started antibiotics. No other symptoms of being sick just the node. After the node went away my throat started feeling like something is draining down the back of it. Not sore and not painful. My question is could this be ARS? Also was I at risk having protected sex? What are the chances? Also the condom did not malfunction in any way. Maybe I have read to much and gotten all worked over nothing. Well thanks in advance.
