I am 19 years old, 5'2 and 95 pounds.
For about 2 weeks, I've been experiencing pressure in my chest when I lay on my left side; pressure causing trouble breathing.
3 nights ago, I had been asleep for 3.5 hours, when I woke up with excruciating pain and pressure/tightness in the center of my chest, and underneath my left breast; and could barely breath. (While laying on my back). I also had pain in my left shoulder.
The pain and pressure/tightness lasted for 6 minutes, ending as I was reaching for the phone for help.
I haven't gone to see a doctor, because it hasn't happened since; although I've still been having pressure and trouble breathing when laying on my left side. I haven't even told my parents about it, because of all the stress of my previous medical bills.
Does anyone know what this could be? Will it happen again??
*I have medical problems, unrelated to my heart (as far as I know).
