The Monroe Institute is a facility that’s researched various frequencies and studied altered states of consciousness, remote viewing, out of body experiences etc and the CIA enlisted their help to train their agents to utilise these abilities as spy tactics.
In one of the declassified documents from 1977 released by the CIA, it's mentioned that you can use the code 55515 to reduce pain from the physical body.
What You Do:
Focus your awareness on where your physical pain is coming from and repeat the numbers 5-5-5-1-5 until the pain is gone.
Anecdotal reports state an almost immediate reduce in pain after using this method.'
Placebo effect? Or Re-coding your body?
I did a bit more digging at it looks like there’s a gene discovered in 2000 (over 20 years later) that relates to pain perception also identified as 55515 
A NCBI page on this specific gene writes "These channels have been implicated in synaptic transmission, pain perception as well as mechanoperception."
(Mechanoreception is the ability to respond to certain kinds of stimuli). This gene is expressed predominantly in the pituitary gland.
Interesting right?!

I had pain in my stomach since 2015. Yesterday a therapist did this with me and the pain disappear. As yet it has not returned. To say I am blown away is an understatement.
I have severe arthritis in my left knee hurt for months I started saying 55515 over and over concentrating on the knee and now after 6 months no knee pain and it hasnt come back doing this now for everything else
