Hello rms13,

You mention "sports phsyio" in one of your posts. I think that is a good direction to head. Of course proper bike fit can help. The slight change in position is probably aggravating issues that were already there.

I have had lower back pain myself that has always been attributed to tight muscles, specifically, hamstrings and calf muscles. Not an expert by any means, but I would invest in several half hour massage sessions with a licensed massage therapist. Try to find one that works with a chiropractic doctor.

We probably all tend to over exert ourselves from time to time and this will compound physical issues. I have experienced this myself over that past two three weeks. Being currently between jobs, I have had plenty of time to ride etc. so my lower back has been screaming at me a bit. So when stretching or having my wife help with passive stretching did not work, off to the masseuse I went. First 30 minute session made a major difference in how I felt. Will follow up with one more or two if needed.

If you have med insurance, check to see if they will cover the costs, mine does.

Good luck!

Mike
