Fairly frequently I get this weird tickling sensation, anywhere from inside my armpit area/underneath the top of my arms, to in my chest, behind my boob. Only ever in the left side.
It doesn’t hurt, but feels ‘cringey’/uncomfy in the same way that pins and needles is (but not the same feeling). I want to scratch it but it feels very deep inside my body.
Anyone else, and any idea what causes it?
I’ve worriedly thought cancer before but it’s not a symptom I’ve heard of, not without pain. I do get chest pain sometimes but I’m fairly certain that’s due to anxiety.
