Severe pain may be due to delayed wound healing or infection of the wound. Swab samples of the wound/incision line have to be taken and sent for culture-sensitivity along with blood culture to isolate the infecting organism.Then specific antibiotics-topical as well as oral have to be started.Till the report of the culture comes,the doctors will start with broad spectrum antibiotics.
Severe cases may require dressings for a longer period of time or even a resurgery to stitch the wound.
It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided. For exact diagnosis, you are requested to consult your doctor. I sincerely hope that helps. Take care and please do keep me posted on how you are doing.
Thanks so much fro your response. I am now six weeks post op and it looks like the edges are starting to heal a bit. Today is the first day I don't have intolerable pain. It is at a dull roar. I have been seeing the Dr weekly and they are keeping an eye on the progress.
