I fell on my back over a month ago. After a week I started having pain under my arm and upper back. I had an xray and my spine is OK. They said I must have strained muscles in my back. I am having physical therapy but it is not helping. Do you have any suggestions?

I feel for you, I severely strained my back, I also had therapy, I also had some chiropractic treatment. Ice your muscle frequently, no heat, if you don't have a prescription for a muscle relaxer and anti-inflammatory medication get one. Those medications did more for me than anything. It took many months to heal...and even now I have days that I need ice and anti-inflammatories.
