Hi,my mom's been having a chronic back ache for many years.she suffers a severe pain on her pelvis that starts from the waist and continues to her legs.and also her legs are getting thinner & weaker everyday! so that she can't stand or walk for a while. one doctor said that she has a herniated disc and her lumbar vertebrae is worn. another one said that sciatica vessel has been blocked,so the blood circulation has been slowed toward her legs, we tried many different treatment but non worked. will you please help me?what should we do for her treatment? Thanks, kind Regards.
