My pain doctor wants to try out PRF to stop a nerve from firing which is triggering my crps.

Has anyone had this done and did it help? She stressed that its totally different than RF as it dosent reach temperatures to kill the nerves just pulses them so no damage is cause. She has performed PRF on other patients with similar symptoms and crps with good success.

I am unsure about this as my leg is so sensitive and reacts to everything let alone sticking a needle in the place with most pain. The needle is only 5mm and will go through torture if this will help me.
