It doesn't sound very characteristic of Navicular at all.
Navicular has been found in horses as young as a yearlings, but generally shows up within the ages of 10-13.
Horses with navicular tend to stand parked out, keeping as much weight off their toes as possible, or will stand like that and paw with one front foot. They are very relucant to move because of the pain, therefore will not walk out of it.
It is generally found in horses with smaller feet and big muslces, or a too high carbohydrate diet and kept in a stall too much.
Quarter Horses are mostly prone to Navicular because they tend to have a smaller feet with a much higher top body weight.
There is no direct cure for Navicular, and turn out time will not help the horse, as it does not prevent the bone from rotating any less and horses are often relucant to move.
Bute is the most common drug for relieving pain, although there are many drugs that open the vessels to the foot to increase blood flow and circulation.
Without knowing how much turn out time and/or excerise your horse gets, he could just be stocked up, and as he is able to stretch himself out he becomes "un-lame".
It could be arthritis, a bruised sole, or simply a pulled muscle or tendon from playing too many horsey games.
I would suggest nerve blocks and hoof testing through an experianced veternarian to start, as they can then begin to pin-point the location of the pain, and then move onto x-rays if his lamesness does not get any better.
I would not forget though, to ask your vet to consider other joints in his legs (knees, shoulder's) when doing a physical to ensure the pain is not coming from any other joint.
