Hi, My sister went to Ruby Memorial Hospital, WV, (ENT Center). Her doctor told her she had a severe sinus infection. He numbed and scrapped her sinus, vacuuming out the infection, and gave her a prescription of augmentin. She was told that she should feel better in two days. She is not feeling better, she is have a great deal of pain. No bleeding. She is complaining that her face, teeth, and head is hurting, and that she feels dizzy sometimes. Is this normal? When should she be feeling better?
