See your doctor: These are symptoms that require a thorough evaluation by your doctor. Only after obtaining this informstion, can he/she adequately diagnose and treat you.

Revisit: I think you should revisit your doctor so your wound can be evaluated for a complication. It may be as simple as some skin irritation in response to an adhesive dressing or it could represent wound breakdown or an infection.
