Hi and sorry you haven't been feeling well. You can carry Staph in your nose and it can be normal. It is also often on the skin. But if you get sinus symptoms then you may want to get treated because you also have the gram negative bacteria too. Usually, you don't have the gram negative bacteria in the nose. Klebsiella oxytoca can become resistant to antibiotics as well. That may be what is causing the nose symptoms or sinus headache since there was a high number of it. As for the other symptoms do you have a fever? Any pressure in the sinuses? Any swollen lymph nodes? Any wounds anywhere else? If not I don't think it is a rush to get it done but you have a general feeling of unwellness then you should get it treated. You might see an infectious disease doctor and give that person all your symptoms. They could get a MRI to make sure there isn't anything else going on. But it is probably the sinuses. As for arthritis you could try a gluten free diet just to see for a few months. This worked for a friend. Have you had your blood sugar checked and is it normal when fasting? You could get some tests done if the gluten free diet doesn't work. But I would be careful about going to a rheumatologist. I personally don't trust them. I have had two of my friends get mis-diagnosed with lupus. It is the #1 mis-diagnosed disease. I am just wondering why your muscles /joints ache. Are you on any medications? Also, if you have a high fever ever get a blood culture? They won't do it if you don't have a high fever.
You can get some things done like anti-DNA, ANA, complement, anti smooth muscle etc. these are all types of tests for autoimmune disease. But a lot of people are positive for ANA. Another thing, have you ever been tested for lyme disease? Where do you live? Have you been walking outdoors etc.
thanks,
