Since last 1 month, m feeling very tired, tingling and numbness in both hands and legs, joint pan in lower back and both legs, crawling sensation in back, headache, wrist pain while working on computer. I consulted general physician and he asked me to test b12 & b6 deficiency test. My cbc count report is normal but b6 & b12 deficiency is severe. So doctor suggested to take b6 folic acid capsules for 1 month. Also he asked to take b6 and b12 injections every week till 5 weeks. Till now i have taken 3 weeks injections but still m having above symptoms. Pls advise what to do
