Chest Pain

[Guest]

I'm 37 years old and have high blood pressure high cholesterol,and I'm obese. I'm on medicine which controls these things. I was also a smoker until I quit in January of this year.I started going to the gym trying to get in shape and I'm taking it very easy. I'm having pains in the left side of my body, not just my chest but my shoulder,arms and even my back. The pains are not always the same sometimes it is like an ache and other times it is more like a piercing feeling. By the way I don't have any of these problems when I'm walking or using the exercise equipment. Do you think I should have this checked out?
