Hello, I am 27 year old. I met with an accident and when I visited the doctor, he looked at my nuckles, elbow, and foot digits and said they appear pigmented, may be due to B12 deficiency and advised me to go for a B12 test and to my surprise, I found the levels to be low at 171 and then my doctor put me on vitcofol 2 ml injections every 3 days for 15 injections and then he said he will put me on some oral medications. I am planning to conceive, please suggest if this deficiency leads to infertility and if these medications will permanently treat the deficiency. Thank you in advance for your kind suggestions!
