Thank you Marinka. When I had my arm reviewed, cause that surgeon was also specialized on spinal surgery, he said I would be best to get some physiotherapy to strength the core muscle as you said. Your sciatica is a lot worse. I can still walk around but with pain shooting down leg and in my back to pelvic region randomly. It is bothersome as I can't fully concentrated at work. I guess I would need to start some medication along physio. I just was very reluctant to try medication after knowing too much what they could do to you... thank very much for your concern. Hope you feeling better too!
