I have never experienced that problem while cycling. I have had neck pain from the front leaning rest position. I have had hand pain, which I try to prevent by covering handlebars with closed cell pipe insulation. I found that the heavy, clunker mattress saddle for $12.00 greatly alleviates saddle soreness. I have found that most shoulder and arm pain can be prevented by working out with weights for a period before going on a long tour.
That problem you mention sounds a little more serious. I had not heard of it before now.
