Chronic limb pain after amputation?

I would need to know more to give you a good answer, but from what you have stated, has he tried using a TENS unit? That is used for severe chronic pain.

it could be phantom sensation which is a bit different from phantom limbs. It usually effects the areas were the surgery was. ( Scar lines, plates, bone graphs, etc) hurts like hell some times.

There could be nerve damage try to get in to the hospital to see if there could be any circulation or nerve problems. I had serious nerve problems that cause my stump to be pain and it gradually got worse until I couldn't walk or sleep because the pain was that intense prosthetic or not. I had surgery and while I still have some pain in the femur from time to time the nerve pain is gone.

Get an X-Ray done if one hasn't been done in a while. Bone spurs and Bone growths can cause pain in above knee amputees I had one removed only to have it grow back.

I'm guessing he's tried pressure wraps on the limb, that sometimes works.

If I knew what sort of pain he was experiencing it would be easier to figure out what route to take.

Either way I think if you can get into a Specialist that would be your best bet. I know doctors are a pain in the but some times. Trust me I had 5 revisions for nothing all because my previous doctors were too chicken to amputate, some reason it's a dirty word in hospitals. THey like to patch things and not fix the problem. but there is no need to live in pain for years

There is not enough information here to be more precise. I am sure he has been in a physical therapy program at one time or another. You might want to consider another shot at that. They can use techniques to heavily stimulate the area. In doing so the input into the nervous system gets to be too large and it shuts it off. A simple way to look at that is wearing a watch or other piece of jewelry for the first time. It is annoying but after a while the nervous system just shuts it off. So by using these stimulation techniques that will be shown to him the level of pain can be decreased.
