Is it possible that you some how over-exerted your left side, Donna?
If so, heat alternated by ice could help... and an anti-inflammatory (aleve is my go-to, but if you aren't able to tolerate NSAIDS tylenol) with some light stretching of the effected areas. I suggest this because you describe muscle pain.

I'm sorry that I'm not as familiar w/ your medical history as I should be by now... Please explain, only if you're comfortable, of course.
Have you been prescribed exercises for this area in the past?

Whether or not you have been seen for this before or not, If it doesn't resolve by Monday, my first go-to would be the doc you saw recently, since it is his domain. Ask the secretary to speak to the nurse, who should share the info with your doc. You should get a timely call-back.
Your doc isn't likely to be bothered since muscle and joint pains tend to disappear and reappear when they want. It's not likely to be a unique situation.

I hope you receive some relief soon!!!
