What is this???

UPDATE: I just realized the only new thing I have been using IS the palmers coconut oil 🤦🏻‍♀️🤦🏻‍♀️🤦🏻‍♀️ I had been using it for a few days so I guess It never occurred to me. Thanks ladies!

This morning I was cleaning and noticed my elbow was super itchy so I looked and there was red little bumps on it. I put some Palmers coconut oil to help soothe the itchiness and it did. The itchiness went away then I took a nap later on and woke up with more on my thighs. What could this be??? I applied the oil again and it’s no longer itchy.
