Some people lactate through the skin of their armpit after giving birth.
"Ectopic axillary breast tissue" is where breasts stretch out beyond their usual boundaries, often expanding sideways into the armpit. Pregnancy doesn't cause this, but lactation can make it show up – some people find that milk travels to their 'pits when they're breastfeeding, and others even end up lactating from the pores underneath their arms.
I should know I'm a surgical tech.
So, you're semi awake and rebelling against the government? lol I know it's just a typo and that you meant to type "sedation", but the thought of "sedition" that you don't remember was too funny to pass up! It's a shame that there's no way we can go back and change our errors. Heaven knows I'm made my share and then notice it when it's too late!
