Hi, may I answer your health queries right now ? Please type your query here...I have a seven year old son that is presenting with bilateral calf pain. Neither calf is swollen, red or warm to the touch which would be indicative of DVT. He was exposed to a child this weekend that was ill and since has ran fever and exhibited flu like symptoms. Other than Benign Acute Childhood Myositis After Influenza, what other causes should be investigated?
