Chest pain deep left side below. Pain.

Im having chest pain whenever i smoke or missed any meal or having any tension and getting brups.also having high heart rate and gettint pain not near middle of chest. Left side of chest deep corner . And its going after 10-15 mins. Its started from jan. i smoked weed heavily and got chest pain since had food vomit since then I'm having this and panic attacks. I get panic when my heart rate increases during physical activity or anything. Im national badminton player. Im having so much scare to start practice as it may lead to heart attack something. I always check my pulse in neck. While playing normally it became my habit I couldn't tolerate high heart beat. And getting acidity after that. Few brups removing pressure and pain.
