more exactly i heard that ARS presents with swollen nodes and several other ARS symptoms at the same time. not as an individual symptom.completely on its own.i have a slightly swollen node left neck ,i had 1 in right armpit,gone now,i havent prodded it,the left armpit is very little now due to not prodding it but all 3 were there approx 4 weeks after an unprotected sex episode.so please tell me if the lymph node uilaterrally alone is a known symptom of ARS.i have had no other signs of ARS and am now 2 mnths post exposure.still a mild sensation in left neckneck and some days[it comes and goes]left armpit.the other fact id like to know is ARS symptoms present for approx 2 weeks so the nodes would have gone in 2 weeks or do they continue as opposed to other ARS symptoms
