I have had strange spots on my left cheek (some used to have pus, but these went on their own accord), these have been there for about a year. It started at a small tiny spot, then a small rash which was hardly noticeable, then it spread into more spots at a rapid rate. The area around these spots are slightly darker than the rest of my skin. The area feels rough, and it's slightly tender in some areas (the larger spots), these don't excrete any fluid but before the bigger ones used to be whiteheads.
Around this time, I went to a doctor about it and she diagnosed it as eczema (I used to suffer from eczema as a child).
She gave me Hydrocortisone cream to treat it and told me to come back , however despite using it for the time she specified, the spots show no sign of alleviating.
I have tried exfoliating my skin, and using spot clearing cream. But it only makes the outward appearance of my spots smoother.
Here are some pictures if it helps - I hope they are visible enough:

I am pondering the possibility of it being acne, which I've heard is common for people of my age.
