I have been bearing some body pain for a few months. I consulted doctor and he provided me D3, calcium and folic acid medication for 2 months but it didn't remove my body pain. I was also feeling some sensation in my feet a sometimes on hand (while sleeping). I delayer decided to go for a routine full body check where I found that my b12 level is 174. I visited dispensary and doctor gave me a tablet name Methylcobalamin 1500mcg for two months. Is it a sufficient medicine to recover from b12 deficiency as I am pure vegetarian? Kindly advise.
