Total Health Care has offered to help with Peripheral Neuropathy numbness in my toes feet and ankles. There procedure is Marcaine injections, five in each ankle then a combined electrol chemical therapy for 20minutes, twice a week for 8weeks. I have a fib, abnormal heart beat, also a mechanical mitrol valve since August 1998, also Atenolol which is a Beta Blocker , is Marcaine safe for me or would it increase my heart beat? I am also on blood thinner so injections scare me. What is your advise?
