Patient's Query

Hi doctor,

I have high fever for over one week with no sleep and vomiting. Did two PCR tests and they are negative the chest x-ray shows no infection, and my gastro CT is clear. I have been in the hospital for three nights and am currently on Augmentin and Zithromax. But still have a high fever. They cannot find out what type of bacteria I have till today.

My white blood cells are a little high and RBC is slow and the infection marker is very high.

Hi,

Welcome to icliniq.com.

I am sorry to learn about your condition. I read carefully what you sent us and I fear you need some more patience. The antibiotics you get cover a wide range of bacteria, which is a sign they still do not know what exactly you are suffering from. Normally it should now be tested if bacteria are to be found in your blood and other body fluids. These tests may take 3-5 days. If they should return all negative the search has to go on. There are so many viral infections out there that we yet don’t know all and of course, fungal infections are also sometimes the cause.

Did they test you for MERS (Middle Eastern Respiratory Syndrome) too? If not, they should. MERS is still out, rarely but in relevant numbers. So for the moment, it seems that your doctors follow the standard protocols, which is good. But ask them which tests they run and ask them to test you for MERS as well as for other rather rare infections.

Get well soon!

Same symptoms don't mean you have the same problem. Consult a doctor now!
