<s>[INST] My son hit his le pretty hard ( front of leg lower calf). He has a lump not disclosed but now feels a little warm. I am not exactly how long it has been because he hit it one day then reinsured it so not sure but about a4 or 5days. Wondering if normal to feel warm to touch. He does say it hurts f I press hard on sides of lump but not above or below. He has no swelling or redness. Sorry typing errors not dis colored and reinjured. [/INST] Hi! Thanks for sharing your sons' health queries with Chat Doctor! Well, this is a common medical/orthopedic condition as this is nothing but an old blood-filled sac termed as hematoma that has been infected recently possibly due to rubbing/manipulation and turning it into an abscess!Therefore, kindly see your surgeon for some tests and if possible aspiration of the material and a course of antibiotics; that's all! Hope got the answer to your question; please don't hesitate to write to us in case any more queries. Wishing your son good health! </s>
