A patient is suffering from painful highly corrosive burns similar to acid and wheals have begun to appear on the skin?

The patient is likely experiencing a chemical burn, which can occur from exposure to caustic substances or acids. The presence of wheals suggests an allergic reaction or irritation in response to the corrosive agent. Immediate medical attention is critical to assess the extent of the burns, provide appropriate decontamination, and initiate treatment for pain management and potential infection prevention. It's essential to identify the specific chemical involved for targeted intervention.
