What could be the cause of non-itchy red rashes on my torso? (photos)
I've had these rashes for about a week now. They're not itchy or painful, but appear all over my body, especially on my chest, belly, armpits area and back. There are some as well (but little) on my limps. I am eating normally, meaning not eating anything unusual. So I don't think it's what I eat. The rashes are a little rough (like dried wounds) in the middle after a few days (and seems to leave a scar), but they remain red at the sides.
Thank you for the question. It is difficult to be sure from the clinical photos and you should visit your doctor/dermatologist for a thorough history and physical examination for a proper diagnosis.
Some possibilities include pityriasis rosea, secondary syhilis and viral exanthem. But I do advise to see your doctor to confirm the diagnosis.
