Pain under my armpit

I’ve got this pain under my right arm whenever I move my thumb. I'm assuming it's the lymph nodes acting up? There's some slight redness there too, and it hurts like hell if I touch it...

Anyone have any thoughts?

Just a thought: maybe you’ve got some inflammation in your mesenteric lymph nodes... I know that's a classic issue for people who always insist on keeping their hand out the window while driving down the highway...

Of course, that's just me guessing..🙂

Maybe try switching up your detergent. Honestly, that actually worked wonders for me...
