Suggest Medication For Fever Causing Chills & Body Pain

My boyfriend is 19 and out of no where has gotten sick...it started with him being tired and his hip hurt. then the next day he had a fever, chills, body aches, headaches, joint pain, and he was sweaty.after a couple days he went to the doctor when his fever hit 104.3f and he was in terrible pain. the doctor ran blood test and found out his white blood cell count was 60/100 and his platelet coun was low as well. they said it was something viral.....they requested him to go to another doctor for more tests. see my boyfriend doesnt have the greatest diet and he is a sheet metal roofer so he works outside and with metal. the doctor was listing all these scary things that could be wrong with him and i freaked! its been going on for 4 days now and im really worried. he says he feels fine when hes on the ibprofin (spelling) and its the achey body that gets him. i wass hoping someone could ease my fears and tell me what might be wrong and give me advice on what to get him to help him get better....
