I have taken a few days off from riding and it seems to be less sore. Although I have been taking some ibuprofen as well. I may give it another day or so and see how it feels. Process of elimination??

I can see my dr, but I have recently moved and need to get my records of my back issue transferred here, preferably before I see him. Although, if I need to, I will go see him sooner.

My bike is a hybrid. I just made an adjustment to the saddle that put me in a more upright position, but have only ridden it once since I did that. I may try it again and see how it goes.

It does seem like I need to do some more core work though. Walking may be on the agenda as well.

Thanks for all your support and info!
