[/INST] Hello, Pain at shin-bone is very common in athletes and those who are doing excessive physical work. If in routine exercises stretching is not done then it may also occur o a normal person. In day to day life this is generally known as shin splint. I will advise you to take rest from excessive physical activities for at least 7 days. I used to prescribe mild analgesic in such cases like paracetamol. Hope I have answered your question. Let me know if I can assist you further.  </s>
