A member asked:

My husband has red rash on his arm, its a round warm circle with a hard spot in the middle ?

A doctor has provided 1 answer

Bite: This may be an insect bite with a tiny blood clot at the bite site. Spreading redness could indicate secondary infection and a need for antibiotics. Antihistamine medication can be used for itching. It's best to have a physician examine him for diagnosis and treatment. In the meantime apply an antibacterial ointment.
