Denise to give you some more info, I bought mine a few months back because I got tired of the pull on my neck from the camera strap like you described. The blackrapid will move the weight more to your shoulder and because it carries so low it feels much ..MUCH better. A few weeks back I went to the Zoo on Saturday and Sunday, I carried my 300mm F2.8L and 1D IV on the blackrapid for hours on end. It was not much effort at all compared to the old neck strap.

If your not sure, and you can find a local camera shop that has one, try it out. Only thing that might cost you a bit is how you attach it to your camera, I bought another Wimberley clamp to attach mine to the camera. The clamp was more than the strap.
