Any advice for a girl with pain right between her shoulder blades when she rides? I've got a visor on my helmet which I'm considering taking off, though it only extends about an inch if that. I'm pretty certain my bike has been fit properly based on my height, but I've still got this nagging pain in my traps. It's not as bad in the woods as it is on flat bike paths and I don't know if it's just getting back on the bike or what. Cheers for any help!
