I was playing basketball and was sandwiched in between to other players I heard a popping of knuckle sound. Now the left part of my chest is semi sore. When I burp ot hurts. Lay on the side in which i heard the crackling it hurts.  Any advice would be great.
Hi there. Looks like you've sustained a blunt injury to the chest muscles. It might appear sore and painful initially. These injuries are a common occurrence while playing basketball. I would advise you to give it a rest for 3-4 days. Apply local analgesic creams and some ice packs to help with the recovery. Take tramadol 50 mg tablet if the pain is too much or unbearable. Do some slow deep breathing exercises to avoid sudden cramps and you'll be fine.
