i'm as confused as you are. i don't see how any health care provider can say a disease process doesn't exist if they haven't done the appropriate testing. however if your internal medicine doctor has done any blood work on you recently i would assume he or she did in fact test you for b12 deficiency since you'd been previously diagnosed. i think the key here is communication. i'd suggest you make another appointment with your internal medicine provider to discuss your concerns and confusion over the situation. if your provider has blood test results he or she should be happy to share them with you. if not you may ask again to be tested since you're symptomatic. if you don't get satisfaction from this provider feel free to find another one. it's important to have a primary care provider who listens to your concerns and takes time to explain the answers to your questions. all the best to you!
why would one doctor a neurologist says i have prenicious anemia associated with b-12 deficiency and another says no. i was getting monthly injections and now my internal medicine doctor says that i do not have it. i can't get him to test my blood for it again. 7 years ago i had drank alcohol before the blood test and i told the neurologist this and he said that it would not make the b-12 level drop as low as it was. i am tired all the time dizzy numbness and tingling in my hands and my feet i bruse if you touch me my symptoms are worse than they were 7 years ago.
