Hi, I was diagnosed with low b12 and low iron blood levels last year. My initial bloods were negative for parietal cell antibodies, but were found to be positive on a subsequent test. I was given 5 loading doses of vit b12 IM initially and then they were repeated as my neurological symptoms were not improving. My haematologist recommended that I should only receive 3 monthly injections thereafter as any more would be of no benefit to me (according to them). I have also been treated for low vit d and low iron levels. I have been seen by neurologist and have had MRI which was OK , but have to have nerve conduction studies. I have been referred to gastro enterologist also (due to increased risk of developing gastric cancer. Presently, I am still very fatigued and have been experiencing intermittent muscle twitches as well as tingling hands and legs. My hips, knees and ankles are painful. My mouth is very painful with frequent ulcers and red rawness on both sides of my tongue and in my mouth. I feel like a hypochondriac each time I go to my gp . Any suggestions (apart from shoot me now !) . Oh, and my phosphate levels are low again. My gp wishes to repeat my vit b12 and phosphate bloods again . Are all these symptoms related to pernicious anaemia ? I would appreciate some advice , thanks in advance .
