Doc apt isn’t till January 25

So this rash appears on my armpit once a month. It comes on strong like a sunburn. Peels like a sunburn and then goes away completely for a few weeks then comes back. This has happened once a month for the last 4 months. My doc referred me to a dermatologist but the only one that takes my insurance in my area is booked out I’ll January 😭 my pcp did basic blood work and everything there looked fine. He gave me a steroid cream and it does relieve the symptoms a little. But obviously doesn’t stop a flare up! The first pic is today. The rest are just some over the last few months. I have changed my deodorant three times (gel, powder, all natural) I’ve even tried no deodorant at all and still flared up. Also, it isn’t anywhere else on my body. Literally just the left armpit.
