Hi! I just recently experienced a sudden shock of pain on the left side of the chest during a basketball game last night. I normally play every Thursday but it's the first time that I felt this. I was just basically walking when it happened. Although it temporarily went away and I finished the game, afterwards, I felt pain on different parts of my chest while resting on my bad. It wasn't like I'm crying for pain, but I felt unease last night before sleeping. I had to sleep with two pillows at the bottom of my neck and it felt better. I'm 31 years old, 5'8", 170lbs. Trying to have an active lifestyle but I'm struggling via the random pains on my chest. The X-Ray, 2D Echo & ECG all were ok. CT Scan was also ok although i took it 4-5 months ago. I also have a history of acid reflux. Can you help me? Please and thank you.
