HI, I was wrestling the other day and felt a sharp pain on my lower ribs or possibly inbetween them. I stopped training and iced it. Later that day it felt like it popped back into place, causing a lot of pain. It was fine for 3 days, then yesterday it popped again. It was incredibly sore for the rest of the day and night. I was then awoken by it popping back in last night while I was sleeping. I am not sure what this popping is and if I should go to the doctor.
Hi, thank you for providing the brief history of you. As you are feeling this popping thing you need to take an x-ray to check if any bony abnormality or any Cochin Chat Doctor.  Usually these feelings aren't serious with bone but mostly with the muscular weakness. Performing proper costal breathing exercises will help reduce the pain and avoid the popping feelings. As the intercostal muscles can be strengthened by costal breathing exercises, and also it improves the lung capacities. In my clinical practice patients with post hairline fracture comes with similar complaints, and they respond well to physical therapy and breathing exercises. RegardsJay In
