I definitely agree with Ayehasherayeh's advice to look into lymph node cleansing.
It makes a lot of sense since you do daily cleanse maintenance. Lymph system is used to carry toxins out but has no circulation like the blood system, so we must help it along.
Also have you had your Thyroid checked? It is worth looking into (is your skin flaky, hair dry?) I am definitely not an expert, but my husband got a very "swollen" neck after a liver cleanse and zapping, and nothing but time and warm castor oil compresses helped. He was checked at the Vet's hospital and they found nothing. I developed a swollen upper leg lymph (by the hip) - (after same cleansing ) the size of a golf ball, and dry brushing was the only thing that helped. (also went to Dr's they found nothing wrong)
My take is that the lymph system can get overloaded with toxins from cleansing and needs help getting them out. It is only my opinion though - I am definitely not an expert.
I also notice that after cleansings or zappings aside from these swelling episodes, most often I develop a cold or flu within 2 weeks or so ( sameO? sameO? ) I wonder if others have the same experience.
