2. Fluid from Rashes
When a rash becomes more intense, there may be a fluid that oozes from it at times. This is most likely to happen when the patient has been scratching the rash, but may also occur without reason. This fluid can then crust up, making a hard layer around the edges of the rash or across its surface. Physicians may prescribe a topical medication to help ease the pain and any other side effects when this occurs.
