Zoltani: thanks for the insight about fixed gear supposed to strenghten the back. No, it's pain. I love riding, so darn it's going to be difficult.

Ken Cox: yes, I do have medical insurance. I just don't like to see doctors until I run out of options. They just run you so many tests and takes up so much time. Thanks for the workout tip though. I will try that.

Nuhtowel and Motopercane: no, I got my bike online and I bike fitted myself. I have an appt. to bike-fit next weekend. Do you think improper fitting or not fitting at all can screw one's back? I thought bike fitting only helps the legs, buttocks or knees.
