Ok. I live in the South but didn't get to see Carole doing her own injections on BBC south. Have had eight weekly injections since last November with an occasional six week one in between when felt lousy. Three weeks ago got back my numb and tingly fingers, very numb left leg and tingly feet. Not feeling that bad generally but very worried about permanent nerve damage. Had an injection last week and no improvement. Spoke to Martyn Hooper yesterday and he said I should be having injections every other day. Went to my GP today and he said he couldn't do this but I could have another injection tomorrow and be referred to a neurologist. NHS appointment would be probably six months wait. I do have private medical insurance from my husbands work. I am so scared of having permanent nerve damage and now think I should self inject. My husband is going to Germany next week and one of his German colleagues can buy some B12 for me. What should I get? Not sure what I need. I am able to give myself or get someone to do for me. Please advise .
