thanks for your question
Vitamin B complex and Vitamin C
are two vital water soluble vitamins in body. Deficiency of Vit. B1 pyridoxin, B12 usually manifest in form of burning sensation under feet and tingling in extremities along with drowsiness
. So continue taking these nutrients as prescribed. But please do take precautions as take with plenty of water, or with lime juice, avoid tea/coffee at least 1hr before and after medicine.
Secondly please get your Vit b12 and folate level checked, B12 level is usually in 300-900 in a healthy adult female, and if its more than higher side you can stop to take further b complex.
may also cause tiredness and tingling so please get you hemoglobin
level checked for proper diagnosis, till then continue taking medicines.
hope i solved your query.
