I have had botox injections done in my scalene muscles guided under ultra sound and emg. This is a procedure I have never heard of ever before. Have you asked him how many times he has done this procedure, and what kind of success his patients have had? $2000. clams is alot to put out on a procedure that...may work. Good way to start doing research, but I would get a second opinion, before spending that kind of money. Just my 2cents. Wishing you releief whatever the outcome.
Cheers,
Jay
