Hello Carers, I am not a trained medical person, nor do I have specific knowledge of this condition.
I am a "medical Intuitive"
I "get messages" usually immediately when being told or reading or seeing on tv of a condition.
I read recently the story in a "Thats Life" or maybe "Take 5" magazine about a mother and her son experiencing this condition.
The message given to me was that this condition is a result of a Past Life experience.
This condition can be positively resolved with appropriate Past Life Therapy.
I was also given the warning that this must be researched to your own satisfaction and great care must be taken in selecting a genuine therapist.
I pass this on to do with as you choose.
Johnk.
