Sudden Onset Acute Back Pain
Okay, so in a nutshell, I can spend hours on my bike, with no problem. Just last week after 2 hours on the trainer, I was grounded with acute lower pack pain; missed work, the whole deal. Felt better, got on the trainer this morning. Got off 30 minutes later, and the pain returned. Any ideas? Am I doing something wrong? I haven't had the trainer long, and have just started using it regularly. I DO have rollers, and have never had a problem.
The only thing I can think of is that I'm do for a new saddle. Would my saddle just 'quit' on me like that? Or do you think it's related to the trainer?
