Nasal discharge is typically thicker and may be yellow or green, indicating an infection. Cerebrospinal fluid (CSF), on the other hand, is clear and watery. If you suspect it's CSF, a quick test is to see if it forms a 'halo' when put on a white cloth. Seek immediate medical attention if you suspect a CSF leak, as it can signify a serious condition.
