When the inside of your body itches...

[@classymonkee08]

+Lizmarie Osorio how?

[@deathlock317]

that happens to me a lot, mostly my lungs.

[@Porouskilldeathratio]

+Lizmarie Osorio Inside of your throat becomes itchy.. It gives me the urge to shove my hand down my throat to get it (I can get my fingers about 1 cm down my throat, it almost causes me to spew.)

[@magiphobia4688]

+Lizmarie Osorio That's what knives are for.

[@tjashton3722]

While I was watching this video, I was like, “Itching isn’t t contagious!” But, after that, I felt itchy. Well, karma is real

[@Ninjaof1840]

I used to have eczema, an itching-like skin condition. When I moved to a hotter, more humid climate, it went away on its own, granted that I needed to take medicine and etc.
I like to slap the spot where I’m itchy, because it still creates a kind of temporary pain, but it doesn’t damage the skin.

[@hyberhyb]

Did anyone else get super itchy?

[@novalmao9849]

Mars-
Incorrect grammar and spelling is just one of my pet peeves, I just feel the need to correct it. It's not hurting anyone when I correct someone's grammar, so I don't see why it would be any different if I didn't comment it.
You didn't need to reply to me, but you did.

[@user-iv6qf6hi4j]

An itch, also known as pruritus, is a general sensation arising from the irritation of skin cells or nerve cells associated with the skin. While it can be a nuisance, pruritus serves as an important sensory and self-protective mechanism, as do other skin sensations such as touch, pain, vibration, cold and heat.
