He was put in a private room called “isolation.” I asked the nurse if he had an infection. She said no, he is “colonized with MRSA.” What does that mean? I recently visited a friend in the hospital.

These are the bacteria that live on our skin, in our nose and mouths, and in our digestive tracts. But they don’t cause any medical problems. In fact, we need these harmless bacteria to help prevent over-growth of dangerous bacteria. 1466952 InteliHealth 2012-12-26 t Howard LeWine, M.D. 2015-12-26  | Ask The Expert | |  |  |  |  | | Archive By Date: Ask the Doc Q&A | Page 1 of 4 | | Answered questions from the past 2 years: | |  I have had type 1 diabetes for 23 years. The published literature I have read states that ideal blood glucose levels should be between 80 and 120. Why do I feel the symptoms of low blood sugar at 80 to 90 when this is the normal range for a non-diabetic? |  Can a woman’s menstrual cycle affect blood pressure? |  My antidepressant isn’t working. What are my options? |  I have high blood pressure. I am taking pills to reduce the pressure and they keep it pretty well under control during the day. However, I wake up in the morning with much higher pressure. Is this normal? Is there anything I can do to lower my early morning blood pressure? |  Is there any connection between blood sugar levels and memory loss? |  I have costochondritis. What causes this? I’ve had no injury, but lots of stress and mental health problems. Can stress bring this on? Is this chronic? |  I have frequent headaches. I don’t like taking pain relievers. I’ve been told that vitamins can help prevent headaches. Is this true? What about other natural products? |  y 13-year-old daughter has been diagnosed with a hemangioma. It looks like a wart, and about the size of a pencil eraser. It’s just above her left armpit on her shoulder. What would cause this to happen? Is there anything we should be concerned with? Should it be removed — or will it go away on its own? |  My six-month-old daughter started to have seizures. She had 3 on Thursday, 20-30 on Friday, 2 on Saturday and none since then. All she does is stop, roll her eyes to the back of her head and then cry. We are waiting on the results of an EEG. But can you give us more information on what could be happening and why? |  I recently had a severe reaction to amoxicillin. I had to go to the hospital, where I was given Benadryl and cortisone through an IV. My doctor tells me that I now have "serum sickness." I have joint pain, fatigue and headaches. What exactly is “serum sickness?” | | | | |
