To my knowledge, traditional Ericksonian techniques are not of any use in the relief of Arthritis pains... and am not sure Erickson himself worked with any such cases...
In such cases, the threshold of pain increases with movement... so, even if u succeed in removing such pains, it will be very temporary...
Too bad Hypnosis came to a halt a quarter of a century ago... and what u see in this site is just the same old techniques... in a little while u will discover there is nothing new...
Too bad, the Administrators are not "Cripples"... though I wish they were...
