After the surgery, it has been observed the wound heels up in their own way but the doctors take the recourse of antibiotics to expedite the heeling process. These antibiotics are well tolerated and are prescribed by the doctors after examining the patients.
In your case, though the course of antibiotics was followed, but the results are not encouraging. The following points need to be considered -
1) The antibiotics prescribed by the doctors should be taken in time and any deviation of the time - schedule will cause less working of medicine but if such a negligence has taken place frequently during the course of taking antibiotics, it may not work at all. In that case, you meet your doctor/ surgeon for the review of the medicine and if needed, he would change the medicine after examining your wound.
2) If there is elevation of blood sugar beyond the normal range, the healing process gets delayed. You may confirm the same after getting your blood sample tested in relation to your sugar level in the blood.
3) Sometimes, it happens that some foreign materials are stuck up and is lying in the operated region. This would be needed to be removed after thorough dressing. Hence a further consultation of the doctor is needed.
4) In case, you are not getting positive results after two or three sessions of your doctor, take an appointment of other reputed specialist.
