Thank you all, sorry for the delay been caught up with his care and Daily life. Nothing difinitive that they believe caused it. At the very least I remember in may he slightly rolled his ankle in gym but that's it. He's been out of school now for a week and 3 days. And I have him signed up for intermittent home instruction. On Friday he goes in for a full body bone scan. To clarify the diagnosis. I'm just hoping they find something. All roads have been a dead end it seems lately. And I have also found a counciling center to try. I'm hoping it will bring comfort for us. They have him on prednisone and neurontin. Which had shown side effects. ..so now just taking prednisone till its finished and then start neurontin back up to see if it might help. I'm besides myself. Thank you for that link, I will be going to check that out next.
