Hi
Thanks for writing to the forum!
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. An orthopedic specialist can diagnose this for you.
Hope this helps. Please let me know if there is any thing else and do keep me posted. Take care!
Does the pain raidiate to your back? Have you been eating high fat food? Are you passing any blood in your urine? Or is it hard to pass urine? Sounds like maybe a Gallblader problem or Gall Stone problem ? Try watching what you eat for the next 24 hours if you develope a fever seek medical attention. If the pain eases up by watching your diet you could have gallblader issues, if the pain increase tonight go to the er you could be passing a gall stone and this could put you in a LOT of pain.Hope this helps.
