I was suntanning one week when I suddenly broke out in patches of what seemed to be "ringworm" to me on my abdominal area. But as time continued it seems it has spread to the rest of my back and torso with small red dots. It doesn't itch but it looks horrible. It has now reached to my neck. I have been applying tinactin but it seems to be calming on some days and on others these small dots just seem to spread and flare up worst. What could this possibly be?
