First of all some background info:
i am 16 years old, i exercise regularly (5 times a week: 3 days Interval running and 2 bodyweight training).i stopped doing exercise and started eating really badly (fatty foods, bread cheese all that stuff) about 4 weeks ago and last week i started doing the above mentioned routine again.
So 2 days after beginning with my routine again i started having some mild pain in my left arm, all around the heart area (going from the left chest all the way to the upper left back) and the left side of my neck. the pains in the areas around my heart are like pinches, sharp pains in ceratin spots that are only there for one second but sometimes it was also like a pain that would be there for a few seconds on a larger area one my left pectoral.
My left arm was feeling weak and numb, but i could still feel my fingers and i would also feel like needle pricks on the opposite side of the elbow, on the inner side of my bicep, on my forearm and on the root of my ring finger.
Whenever i got pains in my left neck, it was also like a ***** but lasted for 3-4 seconds and was way more intense.
i've been literally worried sick that i may have heart problems/ a heart attack. i went to the hospital at midnight 3 days ago because i couldn't sleep because i was so worried. the doctor just checked for a problem in my ribs or something and didn't check my heart and sent me home with deflammatory pills for muscle pain.
When i was on my way to school yesterday i started feeling pain in my left arm and started freaking out (o yeah i've had anxiety attacks every one of these days, nausea, feeling down, freaking out, sweating, thinking im dying) and decided to go to the doctor. the doctor used the stetoscope around my heart and then had me get some xrays of the chest. when they came back he just said that it was probably a pulled muscle or something.(cont.)
