I have a semi circle shaped skin rash from 4-5 days.. it's red and itchy when touched..It's situated between my neck and chest. It may be getting drier. Is it a common rash or should be taken more seriously

The semi-circle shaped skin rash that is red, itchy, and situated between your neck and chest for 4-5 days may be a case of ringworm, also known as tinea corporis. To treat this, you can use an antifungal cream like Clotrimazole 1% twice a day for 2-4 weeks. Make sure to keep the area clean and dry. If the rash does not improve or worsens, it is advisable to consult a doctor for further evaluation and management.
