You have the symptoms of the cold, but you're not contagious. Also I would suggest that cold symptoms are that awful sick feeling, achiness, sore throat, and runny nose. I don't think it would include vomiting, diarrhea, rash or any other symptoms associated with flu or more serious diseases.
You CAN medicate, but its one of those colds that is so bad that you still feel wretched after medication.
