Edema (swelling) is hard to pin down sometimes because no matter what causes it, gravity often makes it move lower on the horse so it is most often seen in the belly, sheath, udder, or lower limbs. Most of the time, edema in the limbs is due to standing around and not moving. My guy tends to get it worse in one leg than the other, but it will look much better after turn out, lunging or a ride. His is also not hot and he's not obviously off. Those kind of look like wind puffs. Do you notice it looking better after he gets out to move? If so, something is keeping him from moving around which could very well be pain.
Even if you don't notice him being off, lameness is often hard to catch and mysterious to diagnose. It takes a skilled pro to see it a lot of the time. Maybe time for a work up with an experienced veterinarian (note they are not all created equal! ) Good luck, kind of hoping it's all related because it's an easy diagnosis for you, vs multiple problems. Hopefully if it is the hocks, all he needs is the semi annual "lube job" to keep him tuned up!
