Help for Medical Accommodation

I've been feeling unwell with a fever and I have an exam this upcoming thursday. Does anyone have experience getting a medical accommodations note from dialogue or tia health?

I don't feel like going to get a doctor's note in person will help me improve in my current state, especially since I still have more exams afterwards and would like to recover soon.

Also, is it likely that a fever is enough to allow me to take the makeup exam, I've never needed an accommodation in the past so I'm unsure how this process works.

Thanks
