i had never even heard of desensitizing.....
I just did a little search on google and found this...http://www.bagelhole.org/article.php/Health/315/
they said a lot of things about treatments causes, etc..and then I saw this:
|. Consult Midwest Allergy Associates, Inc., 85 East Wilson Bridge Road, Worthington, Ohio 43085 (Telephone: 614-846-5944) for more details on a Hypersensitivity Testing and Desensitization Program.
You might want to call them for more info..
I'm totally in the dark on this topic, but if you want me to help research I will.
I'm sorry I couldn't be of more help.
maybe hilary will know more... we just need her area of earth to be in daylight. It is nightime now. very late.
