If anyone can help me out, please give me an idea of what this rash is?

I posted this question on here a few weeks ago, but, the rash hasn't gone away even after changing clothing/soaps/everything. In fact, it is now spreading down my leg and into my calf. There's no real itching unless I start scratching it myself. It's red, bumpy and patchy.

There's no real itching unless I start scratching it myself.
It's red, bumpy and patchy. It doesnt blister or weep.
I've put several creams on it to no avail.
I have a doctor appointment soon, but, the fact that it is continuing to spread only down my leg(only my right leg, not left, and isnt going up my abdomen either) is sort of concerning.
There aren't any other symptoms as far as I know, no fever at least.
I have been way more tired than usual but otherwise, no noted things that signify illness like cough or anything.
Does anyone have any, ANY ideas of what this could be? I'll take anything.
it's not letting me add a photo so here's the link to it
