Random rash help!🥺

Soooo I’m a tad bit confused on what’s going on. At first I thought it was my eczema but they seem to be more raised from the skin and I actually have more on my body. My lower back was the only thing I had but now it’s all over my back. I have this for about a month and it seems to be getting worse. I haven’t changed anything with my laundry soap or any hygiene products so that can’t be it and I’m not sure if I need to get this checked out or not or if I can find answers elsewhere. Please help if you have any ideas🥺
