I have been having chest pain for a few days now, off and on...any suggestions?

I have had this type of pain last December a few times, it was a pressure type of pain, that went down my left arm, but it went away. I have gotten it here and there since then, but the last couple of days I have gotten it again and now it seems worse.
I couldn't sleep last night because of it, and because I was really worried too. I described it as someone squeezing my heart, but not so bad that I felt I needed to be rushed to the emergency room. My family thinks it may be gas, but this has been on and off like I said, and I don't think that's what it is. I know I should call my Dr. and I will, but I'm just seeing what other's thought. Two weeks ago I was in the Dr office and he said my heart rate was 116 which was high for me. Anyone have any advice for me? I'm 32, 5'2 and I weigh around 135.

You really must get to an ER and be tested and do not take just one doctor's advice on this either. Women are often dismissed when they have real heart attacks. You are young and need to be taken seriously to prevent damage to your heart.
Better safe than sorry.
Good luck.
