A
vitamin B12 level of 152 pg/mL is low, and tingling/burning sensations in the legs can occur with B12 deficiency. However, after only two injections, symptoms may not improve immediately—nerve-related symptoms can take several weeks or longer to settle. Muscle cramps can also have other causes, so persistent pain should not automatically be attributed only to B12 deficiency.
Next Steps
Continue
B12 treatment as prescribed by your doctor and get reviewed to confirm the appropriate injection schedule and the cause of the deficiency. Depending on your examination, your doctor may also consider checking CBC, folate,
vitamin D,
thyroid function, blood
sugar and
electrolytes such as
calcium/magnesium.
