question: Hi, may I answer your health queries right now ?  Please type your query here. My left armpit has been itchy for 2 or 3 weeks now.  My right armpit is just fine.  there is no rash or any visible sign of infection.  The left armpit is also slightly sore to the touch and at times feels like there is a lump in it.  Is this something that I should have checked out further by my family doctor?
