Caraleigh;

Littlepaw has done a much better job of answering some of the concerns than I would be able to. As far as the popping, it reminds me of one of the things that my ankle was doing before I went in for surgery back in January. There was so little cartilage left that quite often, the bones would rub against each other and make a popping feel as they slipped off the remaining cartilage and hit bone to bone, very much as Littlepaw said.

I do hope that you are able to find the answers and treatment that your son deserves. So far, the neurologist sounds as if he really does not know exactly what is going on, so he is grasping at straws trying to come up with a different diagnosis first, even though other doctors that you have been to have already ruled them out and concluded that it is CRPS.

If I were a mom, and my son was having a constant problem with pain, I would be pushing the doctor to consider CRPS and do what he can to treat it while it is still early to get the best chance of remission, since other doctors have already made that diagnosis. From there, go ahead and search to see if it is something else. If he won't do that, go somewhere else. I would do what is in the best interest of treating my son's problems, which it sounds as if you are doing that.

I wish you the best at finding the answers, and treatment that your son needs.
