Why Does Metformin Cause Muscle Pain?

Why does metformin cause muscle pain? I am 55 and weigh 160 at 5'4" I was diagnosed with diabetes 1.75 years ago. Within a few months, I began experiencing tendinitis in my feet and left elbow. Now the pain has spread throughout my body. I do not take any other medications. I take vitamin D3, B12, alpha-lipoic acid, fish oil and other vitamins daily. I am a vegan.

I had never experienced body pains nor arthritis before I began taking Metformin. I believe it's causing this condition. It forced me to stop my daily exercise routine. I'd like to know what makes Metformin do this to the body?
