Suggest Remedy For Severe Pain In Eye With Fatigue And Headaches

My 19 year old daughter, who is away at college, is having severe pain in her eye (I am unsure which eye), as well as severe sensitivity to light. She reported that the pain is stabbing at times. She has had a cold for approximately 5 days, with fatigue, sore throat, headache, and severe stuffy nose. She bought DayQuil two days ago, and has been taking that, in addition to Ibuprofen. Also, she recently came home (last weekend) to see our family physician for stress and anxiety, and was prescribed Zoloft. Her current medications are Zoloft and birth control (oral). Recently, the DayQuil. Thank you!
