Suggest Remedy For Pain And Soreness In Abdomen After Surgery

Hi, I have had abdominal surgery 3 weeks ago.. Since being discharged from hospital I have got sever pain in my stomach mainly within the incision & it is infected. I am taking antibotics & it is drying up the infection. I am worried of it. Maybe something internal but my doctor keeps in tellinge it's all normal post operative symsyomz. I don't feel any better in myself n feeling worse each day.
