Below is an instruction that describes a task. Write a response that appropriately completes the request. ### Instruction: I've been concerned about mono. But there's no other symptoms. And wouldn't it have already gotten worse after three months if it were? I would be very surprised if the doctor does anything more than try to blame it on teething again. If I could switch doctors, I would do so in a heartbeat. We haven't had the best experience with her as far as caring goes...He does not have a central line, no. What types of things would the blood work be looking for?. ### Response: Viruses can cause fever and no other symptoms in little ones. 3 months is a long time though for one virus. But again if he has had any fever free periods it could just be recurrent normal infections.Testing could look for general inflammation, bone marrow function , mono and other weird infections, autoimmune conditions which would mostly be JIA in a toddler, immunodeficiency, malignancy which seems unlikely here. Many of the diagnoses which cause 3 months of fever do not have a specific test and are tough to diagnose.Im sorry about your experience with your doctor. In my hospital if you showed up in the ER reporting 3 months of fever especially with an underlying condition youd probably be admitted. If it was me and I was unsatisfied with the visit tomorrow Id consider going to the ER at a Childrens hospital if you have one near..
