B. - hang in there. My daugher had mono and she was out of school a good month. She had a severe case of it. We dealt with the same thing you are dealing with and it's frustrating and painful for the child and parents not really knowing what is wrong and then going to the doctor and there is really nothing they can do since the virus hit her system hard. She was prescribed several medications to ease her pains but that's it, it had to run its course. There were times she was in such pain, body, throat, her glands, headaches and we found ourselves at the doctor 2-3 x's a week. You have to stay on top of giving her fluids and a good supplemental vitamin. Have her rest and not over exert herself, the body has to have time to recover. If she is around someone who is ill, she will more than likely catch what they have. My daughter is now much better and it took a good year. A co-worker of mine experienced the same thing with her son. Rest, fluids, vitamins...God bless.
