21 year old male/ swollen lymhnode under arm. Help!
I recently just noticed a swollen tense lymphnode under my armpit, it's about the size of a walnut maybe a bit smaller. I have had a uti for a few months that was treated with antibiotics. And I recently just changed my soap and that's the day it came like the day after starting new soap. It's very tender and sore to the touch but not red. I am out of town right now so I can't see my doctor
Any advice of what I could do? Or what caused it?
