question: My 5 year old niece woke up with a lump on her posterior/inner thigh area this morning. She complained of pain this AM, the pain seems to be improving and the lump, about the size of a clementine, is semi-firm. She complains of increased discomfort upon palpation of the area. No fever, redness, bruising, I cannot note any puncture wounds like a spider bite. Saw MD today who recommends an x-ray as states she has never seen anything like this. My sister has opted to monitor this for 24-hours and if worsens or not improved will do x-ray. Any thoughts?
