question: My brother in law has been having fever of a morning and of a night reaching 104 to 105. I think some joint pain. He has had blood work. The Doctors are saying its viral. But now I just talked to my sister and he is having some memory loss. This has been going on for about three weeks and she can t get any type of answers, been to hospital. Got fluids twice. He is weak. Think she might take him to a specialist if she can get him in maybe tomorrow. What do you think. Please just asking.
