Neurological symptoms. Change results.

Hello I had nerve tingling numbness and one day had severe pain and couldn't sleep. Tingling numbness throughout body, below head. I went to physcian and he gave me Matilda forte not sure wat was the diagnosis. He said take this and it helped. I took it and felt like everything I had was gone, my vision became clear head clear pain went away. He asked me to take for 7 days and leave it I took for some days and left it and felt better but again after 2-3 days it hit me back and went for blood test and b12 came at 386pg/ml, and d3 was severely low. But I had taken Matilda forte which has 1500mcg methylcobalmin, so my result might have been all wrong. I still have neurological symptoms I did all kinds of test. Please help! No doctor agrees tat supplements can change results.
