Can you lift your hands off the bars comfortably while riding? Too much pressure on your hands, shoulders, neck. If not you need to move your seat BACK to balance out your weight more evenly over your seat. Yes, move it back. You may have to adjust your seat height a little to accommodate and you may have to shorten your stem if your reach is to great and/or raise the stem if your core is not sufficiently strong and you lack flexibility.
