### input:
Since last July, I ve had chronic sinus infections. I took 2 different rounds of 21 day antibiotics (July & Sept) with the sinus infections only to return a few weeks later. I had culture of sinuses done in Nov. and came back positive for Staph. (not MRSA). Was put on another antibiotic and follow-up appt showed fungal infection. I m now on a 15 day treatment (Fluconazole) and 6 week nasal nebulizer treatment (amphotericin) for the fungal. I also tested positive last week for Influenza and was put on Tamiflu for 5 days. Now I have hives developing on my body. All of this is crazy to me....why so many infections (bacterial, virus and fungal) in a short amount of time? I m 44 yr old female, 5 4, 140lbs, non-smoker, non-drinker. Any suggestions on tests to determine if I have an immunodeficiency disorder? Thanks!

Hi and thanks for asking us on Chat Doctor. You have been treated heavily with antibiotics, antifungals and even antivirals - all these can undermine your immune system, making you more sensitive to the environment. Other factors that can suppress or disturb the immune system include sudden weight changes, stress, steroids and hormonal dysfunction. You are in your 40s, of normal weight - unless you have had a significant infection in the past that could have lead to immunodeficiency, I do not see the need to test for it. You could do a baseline blood test (full blood count, liver and kidney function) just to make sure all is well after taking so much medication. I suggest trying to rebuild your immune defense. Start taking fish oil generously (2 - 4 capsules daily), vitamin C with zinc, probiotics and antioxidants to start with. Be sure to stick to a nutritious diet rich in lean protein, vegetables and fruits. HY Chat Doctor.  Where the hives are concerned, you could take a short course of antihistamines. Soaking in oatmeal and applying a pre-college moisturizer can greatly help with symptoms. Use gentle skin cleansers and do not rub at your body with a rough towel after bath. Use soft towels and dab gently. I hope this helpsThank you
