After contracting erysipelas, it is generally not recommended to apply heat, as erysipelas is an inflammatory reaction caused by bacterial infection of the skin, and heat application may worsen the condition, especially if done without doctor's guidance. It could lead to a more serious condition. It is advised to visit a dermatologist promptly after getting erysipelas. Treatment may include anti-inflammatory medications. It is also suggested to boost one's immunity and consume a light diet rich in vitamins and proteins to aid in recovery. Additionally, it's important to rest frequently.
