Yes Thank You. My Daughter Is 22. She Was Checked

Yes thank you. My daughter is 22. She was checked for mono and strep, both negative yesterday. She had flu this year and last.. She has a hx of sinus infections. She already had 2 in the past winter treated with abx. Her throat has been hurting for a few weeks. Now it hurts to swallow. She has headaches she said her neck and back are really paining her as well as her knees she said her joints hurt. She went to an ENT. They said it looks like a sinus cavity is inflamed and they want her to get a ct scan. She is so tired and sometimes she felt hot then cold. I'm not sure but this doesn't all seem to be from a sinus infection. Do you have any ideas. She does have scoliosis. 27 degrees. But normally her back really doesn't bother her. I'm very confused as to what is going on.
