Call your doctor: It may be difficult to determine. This is an allergic reaction, the course and duration may be unpredictable. If the hives have persisted over the last several days, call your doctor's office for appt. They will determine if you need prescription medication. If they are more than 85% resolved after several days, they may cont to resolve, there is occasionally a rebound worsening of sxs. Doc appt

A Few Days: This is usually self limited and should resolve on its own in a few more days.
