<s>[INST] I have a daughter who is a runner, got injured 2 months ago. They thought it was her piriformis muscle and it band. Got no relief from stretching or going to 2 different chiropractors. Went to a ortho doctor a week ago with her back hurting now too. He took x-rays of back and hips. Said she needed physical therapy. She went last week and began running slow again per therapist advice, who thinks this is stemming from her back. She didn t run today but is complaining her leg is hurting as bad as ever and now her shin has sharp pain coming and going to where she has to stop talking it hurts so bad. [/INST] Hello, Cannot say in your particular case, but generally, the location and movement of pain give clues as to what is going on. If it is the back, then there would be back pain and the pain going out from the back. If it is a sore muscle, including piriformis, then poking or pulling the muscle would hurt. Hope I have answered your query. Let me know if I can assist you further. Take care Regards, Dr Matt Wachsman, Addiction Medicine Specialist </s>
