Welcome to our crps family.. I have crps in left arm and both shoulders.I am sorry about your son.. Its awful he has to suffer at his age.. well any age to be honest.. He is very lucky, when i had the nerve blocks they worked for 3 days for me..It took over 5 months for a diagnoses for me..I got the run around.. So be patient.. If they help him.. Try them.. I know someone who they really worked for.. She didnt go with the spinal cord stim.. They wanted her to and she had crps type 2 due to a surgery.. they helper her alot. She had her hand locked in fist position.. The Spinal Cord stim is repeated surgerys.. and he is awfully young for that.. Its going to be hard on him.. Just see what his drs want to do.. Good luck.. were all here for you if you need us.. and him as well
