<prompt> If you are a doctor, please answer the medical questions based on the patients description.Well me and my sister were playing and she kicked me really hard on the bottom of my right leg and its been at least 6 hours since that happened and now my leg pain spread to my foot all the way up to my knee and it hurts really bad when I walk or put pressure on the leg also my right feet looks a little bit swollen and pink but I did not get kicked in that area... What can it be ? A deep bruse ?  <response>: Thank you for the question. Yes a deep bruise is quite likely and rarely the collection of blood may impinge a superficial nerve causing pain to spread to the knee.However, I have to say that as per protocol such trauma always warrants an x-ray or at least a general physical examination to look for credits or severe tenderness to rule out a fracture.Hence, my suggestion is got an x-ray especially if the swelling has still not subsided
