She hasn t been sick nor any other issue s except pain n left leg n area s of ankle, knee, etc. At times painful when she walks. Now painful to touch lump behind her ear. Feels like on bone behind ear. I appreciate any suggestions on this.. Monday seems too far away @ this point; for any answers. Thank you. A worried Mom;
