I have had sciatic problems both sides mountain biking helped, I would wreck and hit up the chiropractor he would repromand me...I have been in the yak for about six years now, yeah I am careful loading and unloading, but for the most part it doesn't bother me, knock on wood...I agree, with the others rent or demo for a few times to assure yourself of the pain if any, then make the decision...good luck, but truthfully I think it will help...
