[Closed] Back pain

I met with a small bike accident 6 months ago, and hurt my back. Though it went away after a while, now it’s back. I can’t ride long distance anymore. Sitting for long, is also difficult. However my doctor couldn’t find anything wrong in my xrays, so I don’t know what to do. My friend suggested physiotherapy, and I took an appointment at a clinic near by called Physio Now ( http://www.physionow.ca/areas-of-injuries/low-back-pain-treatment ). I am a bit worried, as I have heard that if the treatment goes wrong, then there are chances of the pain increasing. Is that true?
