Hello all, I finished a course of 6 injections 4 weeks ago and do not feel any better. The nurse at our practice said they would take about 3 to 4 weeks to work. am I just being impatient. So so tired aching all over feel like I have permanent flu. pins and needles in right arm, toes and left side of my face have not improved. I also went gluten free of my own back to try and calm the bloating and the other nasties. but no change so gone back to the normal diet. Should I be taking supplements to help. Should I try to find some B12 tablets. I am on 100mg Levo and still not lost any weight. Should I send for another private blood test. Thank you in advance for any advice.
