Hi Leelee ,
The symptoms seem to be more of
CostochondritisCostochondritis .
CostochondritisCostochondritis is an inflammation of the junctions where the upper
ribsRib cage pain join with the cartilage that holds them to the breastbone or
sternumSternum - view of the outside (anterior). The condition causes localized chest pain that you can reproduce by pushing on the cartilage in the front of your ribcage. The pain is aggravated by deep breathing , yawning or any movement involving the muscles . Costochondritis is a relatively harmless condition and usually goes away without treatment. But I would recommend that you consult a cardiologist and get an ECG and other recommended investigations done to rule out a cardiac cause of the chest pain . Hope this helps you . Take care and regards !
