Will our client [name withheld] receive any benefit from a Lightworker Protocol Healing session for his strangely appearing allergies? If not, what will be required?

He can receive benefit. This is a function of the presence of a spirit attachment and that is creating an association within the mind of the client and triggering an immune response. The removal of the spirit attachment will help ease things, provided there is not a further association with things in the environment the mind has decided may be the true culprit. But, this should give a time for things to fade and there will be improvement.
