Dear Shilpi,
I have not yet had any pain and am very thankful to be able to say that. Sorry your mother is having such a bad time.
I don't know much about the Ambrotose (Kimgee is the one on this message board who told me about it). But, I just got back from another treatment in Houston. They said some of the tumors shrunk substantially from the first treatment, which must be why I feel so well. The doctor told me the first treatment stabilizs the disease, and one can have another treatment 3 months later to shrink the tumors more.
If you really want to look into Excel in Houston, I would suggest you call there and ask to speak with Dr. Delpassand. He will explain everything and will let you know if your mother's situation can be treated this way.
Best wishes, Marie
