My Daughter Is Away At College And Is Under The

My daughter is away at college and is under the weather. Last week her throat started to bother along with body aches, fatigue and headaches. She went to a walk in medical and they tested her for strep throat which came back normal, and told her it was a virus and that there was nothing they could give her. She has been drinking warm fluids, resting in between classes and eating as healthy as possible. She is feeling worse a week later. Should she go back and have tgem retest her or us there something tgey can give to help her get better? Or is this the normal course the virus takes where she will feel miserable for weeks. Plz advise
