I'm trying to figure out if I need to seek medical attention regarding some patches I have developed.
This all started at least two months ago with a single, small red patch just above my left breast. I assumed the patch was caused by my bra even though this patch was in the area where my bra strap isn't touching the skin. I switched bras for several weeks thinking it was just contact irritation, but this didn't help at all. This patch has expanded and is now a very clear ring shaped patch. The ring itself is red and looks like dry skin and the middle is completely normal. Since the first patch appeared, it has expanded a lot and I then developed two more patches on my right breast which are also expanding. I am now developing two small patches on my upper abdomen.
None of these patches are itchy and I often forget they are there until I see them. I put some tea tree cream on them a few nights ago, but that made absolutely no difference. I do have some steroid ointment, but I hesitate to put any on these patches in case this is a fungal infection as the ointment will worsen it.
Can anyone offer any advice to help me determine if this is Pityriasis Rosea or Ringworm? As I understand, Pityriasis Rosea will clear up on it's own, but Ringworm will not, so I'm unsure if I should seek medical attention because they're not bothering me. Many thanks in advance!
