Hi There, I've Been Experiencing A Pressing Like Pain In

Hi there,
I've been experiencing a pressing like pain in the middle of my chest and flutters around the left side.its been going on for over a month. I have been feeling tired all the time, and weak feeling. I also feel my chest racing sometimes during the day. Even lying in bed at night. I have recently started to experience a cough.
I'm on two different pain medications for nerve damage that happened to my face during a dental surgery.
I'm on Diladid and t3s my question is do you think these symtoms are due to the medications I'm on, I've been on them for four years or should I question if something else?
My email,address is YYYY@YYYY
