Good day, i have insert bite (red patches) lookalike around my body. can it be an allergy reaction?

Doctor can examine: Blotchy appearing reddish rashes can occur when the blood flow in the tiny vessels at the skin's surface change, such as in an allergic rash or a viral rash. Viral infections that cause cold symptoms and other symptoms can sometimes cause such skin rashes. Hives are a rash of itchy bumps that look like many mosquito bites. Hives are a type of allergic reaction. A doctor can evaluate if needed.
