Help!! I've got these extremely sore lumps

Under my armpit I have one on each armpit one is soooo big! Anyway this morning my boyfriend has woken up moaning cause he has a limp under his armpit that's very sore too.. What is this! My friend told me I may have a blocked glane.. But now my partner  has it too I'm so paranoid
It's not a Sti or anything is it ??
