Hello ma'am and welcome.
Although at times the presentation you are experiencing can be considered normal, at times it is an indicator of pathology. There could be an abscess
forming, or any other abnormality. It is best to be physically examined to assess the condition.
In the meantime, try not to touch the affected region, let the area be clean and dry and apply warm compresses to the region. Please schedule an appointment with your surgeon.
Hope this helps.
