Is this eczema?

I’ve been having these sort of rashes when the weather changes from cold to warm, they are dry, flakey and itchy. This year I broke out the worst as in rash wise, I had it in 4 areas, my leg, my upper thigh, my arm, some bumps on my hands and my back. I didn’t go into the doc cause I was convinced it was just a heat rash or eczema. Never been diagnosed so I don’t know for sure. The sites are healing up, but I’m just curious as to what this might be?

The pics are my leg and my arm, not all sites. That the rash is on are listed. I’d say the one on my leg is pretty bad, but it’s healing.

I’m out on insurance, and yeah I probably should’ve went to the doctor. But I’ve been having these “flare ups” when the weather changes from spring to summer. I had one on my chest last year it went away eventually.

I lost my job in march and my insurance ended in April and they needed 100$ upfront to get checked out.

America is so shitty, so greedy. I am a healthcare worker too.
