Would like to know if there is a treatment protocal for cold laser?

My friend has had CRPS since 3/06. First R knee - with scs attemt it went to both feet (in OR while he was under), the last 3 months it seems to have spread to face/neck/shoulders and arms. Then last week the left foot looked like it had been placed in boiling water (massive blisters) the day after a nerve block it started to heal (just like magic).

He has been having cold laser PT (2-3 times a week) at AQ PT in Kenai. It is a long trip from Soldotna to Nikiski pool - I wonder if the cold from travel is making him worse. His dr now wants to try hot laser to see if it would help, but am concerned that it might make it worse.

Currently he is confined to a wheelchair - unable to put pressure on feet since 1/09. He gets nerve block on both side (lower back) every two months. If you have any information on the areas of treatment for cold laser I would appericate the information (just because PT has a cold laser not sure it is being used correctly). CPRS is not a normal problem.

Thank you for any infor you can offer.
