Madmum the foot surgeon I worked for told patients that sometimes an injury to ligaments and tendons is harder to treat than broken bones because it takes them so long to heal. It all depends on the exact injury and if there is a severe tear that needs to be reattached in order to even have a chance at healing properly. Then you do have to consider that our collagen disorder makes us heal slowly and tear easily. I don't agree with much that this latest doctor told you. It seems like common sense that with a foot injury that hurts when you step on it that crutches and limited weight bearing would give it a chance to heal and for the patient to feel less pain. I ditched the crutches as soon as I was able to because I had small children and I needed to be able to get around even if it hurt.
It took me several years to heal from the ankle fracture and the tendon and ligament damage. Keep in mind that mine was fractured, torn, cut and attempted to be put back together with surgery and pins. It was 4 years till I could weight bear without pain on each step. I am NOT saying that it will be like that for your son. I hope his injury is much less severe and he starts healing soon. I am pointing out that your latest doctor's time frame was way off from my experience.
Since you can't get anyone to agree that there even is a problem much less how to treat it I would do what seems to work best for your son. Get a larger tubigrip support and see if he can manage to keep it on. On days I walked my foot would swell and by the end of the day I would have to take it off. It still was worthwhile though because it reduced how often I twisted my ankle when I did have it on. Your son could try wearing the support under the sock or try it over the sock to see what is more comfortable. Good luck to your son in sorting out what things make him more comfortable and let him heal.
