Shoulder/arm pain

I'm a 51 year old female who's experience pain in my should and upper left arm for several weeks.  In the last week, it's extended in to my hand, particularly affecting my thumb. In the last two days, I've also developed a tightening in my lower chest.  I had been attributing all this to pulled muscles -- I distinctly recall stretching the wrong way a few weeks ago and actually hearing something "crack" or pull in my upper left arm.  do I need to worry about any of this?  My blood pressure is normal; my cholesterol, while elevated, is not extreme.
