I am definitely noticing a difference. I have done approximately 5 treatments and not only use it on my hand and wrist, but also on my forearm close to my elbow.  I am in the Orthodontic field and was chairside for 30+ yrs and now work on the technology side of orthodontics on my laptop.  From one extreme to the next with using hand instruments to now controlling a mouse. The treatments are helping and I can’t wait to see if it totally relieves my pain to where I will not have to seek medical attention for it! Tammy from Texas
