You : You do need to be seen and be evaluated for this. Even though you are taking vitamins or minerals, you could still have a deficiency such as low potassium or low sodium. There are other neurological possibilities as well. Please be seen by your doctor for a complete evaluation. If you have worsening symptoms or any new complaints then you would have to be seen immediately.

Calcium : Calcium metabolism or endocrine issues also need to be looked at.
