Hello there Mr Christensen, My mum has had an operation in her back due to touching of nerves a few years ago. She now experiences a lot of sciatica pain in her legs and back. She has osteoarthritis . She is approx 13 stones unfortunately she is unable to lose weight. She is 82 years old and very active for her age. She has taken numerous medications , painkillers, ayurvedic , etc. And also tries and does exercise whenever she is not in pain. Any advice please?
