Hi
Welcome to the MedHelp forum!
Yes, you can get chest pain (pain in your breast area) from throat infections. Throat infection by streptococcal bacteria can cause heart affliction too. Similarly throat infection can spread to lungs and cause pneumonia which can cause chest pain. If it is accompanied by fever then high pulse rate can cause chest discomfort. Antibiotics given during throat infections can cause acidity and chest pain. Pleuritis and Pulmonary embolism are other possibilities causing shortness of breath with chest pain. A CT scan of the chest can rule out both. If you have chest pain please get this investigated.
Chest pain aggravated by laughing yawning, moving in certain directions, stretching 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. It can also be muscle pull. Shingles can also start this way.
Do discuss this with your doctor and get yourself examined. Take care!
You should see your family doctor. There could be something very serious wrong or it could be just one of those weird things that come and go. But if the pain gets really bad, I would do something about it before it got worse.
