. they dont hurt.some are un noticeable but some really do swell. some dont and are unnoticeable. i strongly suggest that let a doctor look at them you cannot diagnose your self on what you see on the internet leave that to the professionals. lymph nodes swell for some other things not only HIV. peace of advise stay away from your nodes. dont touch,prode, or feel them, it will just make it swell. if your symptoms bother you see a doctor.
