Looks like Mother Nature decided to send a "hello, I'm castor oil" surprise to your belly button party! Don't worry, it's not uncommon for the stuff to cause some initial discomfort – just Google "castor oil tummy symptoms" and you'll see what I mean.

On the bright side, if this is indeed the real deal, maybe those patches will arrive faster than you thought? After all, your body is like, "Hey, what's going on with the castor oil, human? Make it stop!"
