Suggest Treatment For Cold And Sorethroat

Hi, my daughter is 21 yrs and not at all overweight, she attends the gym 2-3 times a week and her blood results came back with crp level of 70. She was ill with a cold, sore throat and ears at the time, so could this have been the problem (all other results were normal). She's had another test since (2 weeks after the last one) and we are waiting for the results but I am so worried, so any advice would be appreciated.
