Prolotherapy to the Knee

i've had prolotherapy on my knee, it does help. It works better if your nutrition is better, something it took me awhile to realize.

I've had prolotherapy done on my neck which included injections in my scalp, along my spinal column, and outward towards my shoulders. First, the doctor sprayed on a topical numbing agent, then he injected surface level analgesic so that I didn't really feel the deeper injections. My daughter has had it done on her lower back and hips with minimal discomfort. Recovery time isn't very long, but you do need to lay low for a few days because the body is trying to heal.

damn that looks vicious

can it be done on joint above feet?
