I am commuting to work on a performance hybrid, with a backpack that has my laptop (5.5lbs), power adapter, case (1 lb), krypto bike lock, and lock cable in it. Sometimes I add this or that, but the added stuff is all light. For ex., a t-shirt or long sleeve pullover.
Recently, I started having some back pain and it looks like one of my vertebrae has popped out a bit from my spine (outward, away from my back). I'm riding around 5mi each way and wondering if I can really attribute my back problems to this? Or maybe it's an overall problem that's been aggravated by cycling?
Any thoughts would be appreciated... I wouldn't think that I could attribute the problem to cycling alone, but I suppose so. I really hate the way that my bike feels with panniers on it, so I am trying to avoid that.
