<s>[INST] 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 ? [/INST] 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 crepitus or severe tenderness to rule out a fracture.Hence my suggestion is get an x-ray especially if the swelling has still not subsided </s>
