I have had balance problems for the past one year. I first went to a ENT, they gave me medicines like stugil and vertin-16 for 2 months. The problem did reduce but it is still there. I recently took a blood test and found my vitamin d was only 8. I usually get this balance problem the day before I get a headache. I have noticed that this headache comes due to neck strain, because the ache starts from the back of the head. Since I had low vitamin d, could that be the reason for week neck that is also causing balance problem? I have completed a 8 week vitamin d supplement course. What should I do to strengthen my neck?
