question: I have been diagnosed with pernicious anemia. I have been getting weekly injections for 4 weeks now. I am feeling much worse since beginning treatment. My legs are very weak and shakey, headache for several days, foggy brain, skin rash, itching all over. My Dr. Is stumped. I think I am having a reaction to the injections. She referred me to a rheumatologist today. I asked to be referred to an auto immune specialist. Any suggestions.?
