hello there.. i'm glad that i have found this forum since i am searching for the causes of symptoms that i have for about 3 years already like dizziness, brain fog, muscle & joint pain, cold hands & feet, pain on my fingertips and sometimes loss of balance and feeling of anxiousness.. I had several lab tests in the past and all the results came normal. I also had a gastro-endoscopy wherein they found that I have H. Pylori. Eventhough H. Pylori has been erradicated, the symptoms which I have mentioned are still there. The dr also performed colonoscopy just this month and findings are normal. So when I found this forum, I requested my dr to test my level of vitamin D, B12 and Folic acid. I will get the result by Saturday or Sunday and I am hoping that I can finally find the answer that I am looking for a long time.
