Hello karenl2008,
Sorry to hear about how your mother felt. Unfortunately it is illegal to make diagnoses over the internet. If this ever happens again please take her to see a doctor. They will be able to tell her whats going on and may be able to help her out. Sorry for the delay in getting back to you. We are currently trying to make it more clear on the Ask a Question page that it is not possible for us to diagnose people over the internet.
