After months of negotiations my gp will now only allow a b12 injection every three months. I cannot last more than about 10 days before symptoms return - therefore I SI. When I once mentioned this to my gp she went wild and told me to leave the practice (I negotiated my way back in). Now, when I go for my three monthly injections she will see I am okay whereas I would be crawling there if I had not SI. How should I handle this..... very grateful for suggestions. Meanwhile, a happy and healthy 2017 to you all.
