Granted in order to be hooked up to the machine, you will need to be stuck with needles:
- for the Arterial side and
- for the Venous side
But you can numb the area ahead of time with cream.
Ask you doctor about a numbing cream, I use a lidocaine and Prilocaine cream.
My insurance always gives me a hard time about filling this prescription. So I have a back up of lidocaine cream.
Either way the best way to use it, about 45 minutes to an hour. Put generous amount of cream on the area (glop it on) and wrap the area in plastic wrap.
