Hello,

My name is Sm,mia and I have been smoking marijuana for the past 2 years. I just recently started getting pains on my chest and sometimes it travels like to my neck and head and onto my arms. I got an EKG done and it came out perfectly normal, so its not my heart. These pains do occure more when I argue, get man, or yell. Sometimes i get sharp needle like pains on my left and righ side. I was doing research and my left side of my neck hurts its calles the sternocleidomastoid. Please Help me. Do i need to seek medical attention?
