Any clues to what's wrong?

I have severe anaemia (pernacious) I think. Have very low Vit B12. had caeliac test=negative. My fingers wrists elbows ache. I walk like a penguin in the morning cos my feet are stiff. wear and tear in my knees. can only walk 5 minutes before back pain gets me to stop. Had a mystery healing fracture in my collar bone last year. I am just falling apart. Had a RA test done and it came back clear I am only 31 and my doc was worried it was RA. I am going to see her again on 10 july to discuss what could be wrong. Any ideas or people with similar pains. I will answer any questions asked. HELP

I eat meat and my green veg

I have pernicious anemia. It is low levels of b vitamins. Mine is due to bowel surgery that left my body without the intrinsic factor needed to convert b into my body. The doc prescribed b12 and needles. I gave myself a shot every week for a month, then monthly and now every 3 months. I get my blood tested twice a year for b stores. It would be interesting to see what caused yours, poor diet or the same as me. In that case shots are in order. It is easy to do or you can have someone else do it. It take a long time to reduce your B stores. These symtoms could be because your body has been so stressed as you have lost your B. My symptoms were losing balance, tingling in arms and legs and horriible tiredness.... Email me if you want. Glad to talk with you.
