Redness on arms

Cara

I just noticed these redness spots on my arms right near my armpits. Both are somewhat warm to the touch but don’t hurt or itch. I don’t have insurance until my husbands kicks in since he just started a new job so I can’t really afford to go to the doctor uninsured right now. But I am a little concerned about it so I wanted to get some opinions. I’m definitely not saying I WONT go to the doctor, but I’m definitely trying not to unless it’s severe.
