Having just gone thru a hysterectomy myself I agree with Wendy that the flare ups of the hormones is treated well with rest. I found that my panic attacks, still on going after 2 weeks, subside to nothing with meditation. I still have my ovaries though so the PA's will subside as well as the night sweats.
When my Mother in-law had cancer she was careful to remember and remind others that she HAD cancer, that she did not become cancer. Perhaps this woman needs to be reminded that MS is something she has not something she IS.
She probably also has major "mother" missues to contend with relating to her own Mom and her in-ability to become a mom naturally. Root and base chakra work needed for these issues. You can see this in the fact that she had these female medical problems to begin with.
With your work with her, have you sealed up any holes left over from surgery? Filling the hole within her with light and also checking her energy fields for holes as well?
As for the MS I do not have experience working with this disorder but it sounds like she has much more going on other than the MS. Perhaps working at the smaller stuff would bring her better relief at the start.
Keep us posted on this as it would be benefical to leran about MS. It is a growing disease that we will handle sooner or later with our clients.
Love and light,
Tracey
