Let me pile on here too. Hopefully, when you bought the bike, you received at least a basic fitting for it, assuming you bought it new. If not, as soon as you have room in your budget, find a bike shop with a good reputation for fitting (ask other cyclists, preferably older guys like me) and have it done. Keeping your cadence - how fast you spin the pedals - up helps here too. Aim for >80 rpm; you'll settle in somewhere north of that. I usually average in the 90-95 rpm area, but this is an individual thing.
Best of luck!
