I have a cold that just won't go away. It's been over a month. Can a doctor do anything for me? Most colds are self-limited and last about 7-14 days, so for a cold that has persisted for over a month, I would recommend seeing your doctor to review your medical history and do a physical examination.

Could it be allergies or just simply a common cold? Cold weather is inevitable during the next few months, and many of us will have an infection involving our nose and sinuses.
