On my lower leg there is a patch of rough, discolored skin and its been there for a few years now and has never bothered me up until recently I noticed it started to spread. It is painless and very rarely itchy and when it is, it starts to get dry and crusty. These new patches are a little red/pink and I can see tiny bumps whereas my old one is flatter but with wider bumps and darker than my skin tone. I’ve been researching into it and the closest thing it could possibly be is a mild case of eczema but I have never had anything like this before or anywhere else on my body plus it doesn’t match most of the symptoms online. Please help me figure out what this is :-(
