Hello i got back from the ER, after thinking i was having heart problems. They told me i Had Costochondritis.The pain is in my upper left pectoral. I was surfing a week ago and beleive thats what it was from, as i had a sore lower right rib that has now heeled up for the most part. I didn t have the pronounced feeling in my upper left chest until i had taken some adderall. He said that could trigger the pain. I wanted to know if speed like stimulants could trigger the pain more so? Thank you.
