I had chemotherapy for breast cancer three years ago. I have been on Femara since. I am now suffering from neuropathy in my feet and legs. What can be done to help? I understand that electrical stimulation might help (I currently own a Medea 2500 Tens Unit). Could it be used? I also read that multivitamin B supplements can help. I found one on the internet called WSN Nerve support formula. Is there any point in taking it?
