Back, elbow and shoulders. Do you feel hunched over on the bike or that you are sitting over the handlebars ? Are you tires pumped up to mac air pressure making for a jarring ride ?
For what it's worth, I had a Roam that I could not stay comfortable on for hour plus rides and after trying seats and even Jones H-Loop bars I ended up trading up to a drop bar Toughroad with tubeless tires and a Brooks B17. All my back pain, shoulder and wrist pain and sore butt have gone away and I have 1500 km on it now including a couple of 5 hour rides. Sometimes a different bike might be the answer.
