Welcome to the MedHelp forum!
If apart from chest pains you have cough or fever or breathlessness then causes like pericarditis and pleurisy need to be ruled out. It can also be a clot in lung. However if there is only pain then it may be costochondritis. Chest pain aggravated by laughing yawning and deep breathing goes more in favor of costochondritis, which causes pain and tenderness at points where your ribs attach to your breastbone. The inflammation around the joint area gives sharp pain on taking a breath. This can also cause tenderness on pressing the area which pains. An orthopedic doctor can diagnose this for you. Generally there is no cause. However it can be due to infection, blow, injury, or fibromyalgia. It usually goes away on its own. Otherwise it can be treated with muscle relaxants, and non steroidal anti inflammatory drugs.
Hope this helps. Please let me know if there is any thing else and do keep me posted. Take care!
