<s>[INST] Hi. So I m a runner and I have good running shoes, but recently my left knee will have a killer pain in it. Also, my left hip feels like it s bruised right on top of the bone in only one place and it hurts to touch it or move it a lot. What is wrong and what can I do about it? [/INST] Hello runner! Your sports activities have caused a certain amount of degeneration of the joints with possibility of a cartilage tear in the knee. Its possible the same has occurred in the hip. This calls for rest a to the affected parts. You may use pain medications like diclofenac or proximal along with muscle relaxants. This should be followed by X-rays or an MRI to locate the damage. Treatment will be according to the findings in the MRI. Good luck ! </s>
