Hi Susan
I wouldn't worry about the wooziness after the treatment so much, but the continual nausea could be a sign of a bigger problem. Any chance she could be pregnant? When was the last time she was checked out by her primary care nurse/doc? Could be stress, could be, gulp, cancer. Best to get it checked out.
On a less gloom and doom note, maybe the nausea and wooziness is because she also needs an upper body treatment?
