A.N.
I have a fabulous doctor that utilizes many different modalities. She is wonderful, she was at Clearwater Natural Medicine for about 15 years or more and now she has opened her own practice in downtown Safety Harbor, not a far drive from Carrolwood, just come over SR 60 and turn onto McMullen Booth. Anyway, her name is Dr. Rebecca Lord ####-###-####. She would be able to diagnose your son without invasive techniques like skin testing, which I went through with my son--horrible!
Tell her A. Norris sent you....good luck!
