Client's numb hands during treatment

[BroConiaie]

Hi

A new client has been coming for reflexology for the last four weeks.

During this time her headaches etc and tiredness have improved and she feels much better.
However during the treatments she says that she gets pins and needles in her hands and they go numb. As soon as the treatment ends the pins and needles etc disappear.
She says that her hands normally feel hot all the time but during reflexology they feel cold.
I am just curious about this and would welcome any opinions.

Thanks
