I have a pain in my chest and somewhere in my deep throat, it started two nights ago as i was working on a car on jacks and the car shifted and I had to somewhat hold the car from falling for about 5 minutes, plus I also had to jack the car up with a hand jack quite a few times. I then started to realise a pain in my chest and it hurts when i take deep breaths and is very uncomfortable, also I can feel it when i swallow but it is deep in my throat not where you'd normally get a sore throat. When i wake up its not as painful but once i get up and walk around it started to get more and more painful and is a pain i have never experienced before. Is there any muscles in my chest that i could have pulled or could it be serious and in need of doctors assistance? I am also a smoker about 3-4 smokes a day and 19 years of age.
