Hello doctor,

I started taking Vitamin D and calcium more than I should have in the beginning of the year. Later on, I started to feel weak and dizzy at work, my feet and hands tingle and would go pale and my neck in the thyroid area started to hurt. I have been to the doctor to have blood work, but they say there is nothing significant enough to be concerned, but I still have the same symptoms. What to do?

Welcome to icliniq.com.

In your attached Hb electrophoresis report (attachment removed to protect patient identity), abnormal hemoglobin is not present. So you are not having any abnormal hemoglobinopathy.

Your main complaint is weakness, dizziness, and tingling. So anemia, B12 deficiency, thyroid issue, liver disease, renal disease, vitamin D deficiency and peripheral neuropathy should be ruled out.

I suggest you investigate with serum B12 estimation, CBC (complete blood count), serum TSH (thyroid-stimulating hormone) estimation, SGPT (serum glutamic pyruvic transaminase), SGOT (serum glutamic oxaloacetic transaminase), serum urea and creatinine estimation for further work up. To rule out peripheral neuropathy, your neurological physical examination should be done. According to cause specific treatment can be given. I suggest you rule out diabetes as well by random blood sugar estimation. Meanwhile, you can be prescribed Riconia forte like multivitamin tablet for your problem.
