I am under a rheumatologist who thinks I may have Sjogrens. Still going through the process. He was the one who suggested I have my B12 checked again. It was 197. After another test a few months later was 237. I have been having chest wall pain for a couple of years. The rheumy put me on Hydroxycloroquine and I had a massive reation, skin peeling off etc. This lead to me being on Steroids, which due to budget cuts in the NHS, were not gastro coated. This caused stomach problems. My question, if anyone can help is I have been hospitalized with chest pain twice in the past few months. Its leading to a diagnosis of GORD but could the pain be B12 deficiency. I am going to the rapid access chest pain clinic tomorrow to check my heart further. I am now on Omeprazole 40mg per day so I am treating myself with sublingual B12 and already am feeling better. The doctor would not give me injections as I was just above 200.
