I have a cold. runny nose. cough. and fever 100.2. i also have ra. what should i do?

Rest/fluids: Take care of yourself by drinking plenty of fluids and resting. You can take tylenol (acetaminophen) for fever and body aches. You can take robitussin for the cough. If you get a higher fever or new or worsening symptoms see a doctor. As long as it just appears to be a cold virus supportive and symptomatic care is all there is to do.
