Tinea faciale, questions?

i have recently been diagnosed with a ringworm and was given nystatin. I do not know when I got the ringworm, but I do know that it was quite early. I have been using the cream for around 5 days and it is clearing up. Just because I was not sure I have been putting it on several different spots on my face that were red and pimple like. I have acne at times. The ringworm looks as if it is gone, but other places on my face look splotchy, patchy, and sometimes red. As if it's dry, like eczema. They do not look like ringworm, but with my paranoia i am bound to put it on there just in case. My doctor also told me to do this, because she is lazy. Could these possible be ringworm or eczema? also I have been very clean, but today I have taken a break and I haven't washed my pillow case and I touched my hair regularly today because I am starting to feel more comfortable. But eventhough ringworm of the scalp is rare in adults is it possible I could contract it...eventhough I have very limited contact with my face? Also today I washed my face as a whole when usually I wash everything seperately. Since I am treating it, is it still able to spread to different spots?
