Do vitamin D deficiency leads to body pain and loose stools?

This Premium Q&A, reviewed and published, features a real conversation between an iCliniq user and a physician.

Patient's Query

Hello doctor,

I found I have been vitamin D deficient for the past five months. My vitamin D3 level was 7.04 (too low). So the doctor prescribed DV 60K once a week for two months and then once a month. I have been taking this medicine for three months. I was fine and had no pain. Now already I took 15 pills in a period of three months.

Now I am having pain all over my body. Hand pain, joint pain, and lower leg pain, even I took rest but it is still there. I did blood work. Everything looks fine and within normal range, except for high cholesterol. My calcium level is good, 10.1 mg/dl. I feel tired and fatigued all the time. I've had watery stools for the past three months, and I know this is not diarrhea. My stool is clear, and no WBCs are in it. My urine is clear.

I got a gland on the floor of my teeth and a small lymph node in my neck. I completed an antibiotic course for it, but it is not going back to its original size. My question is, why am I having pain all over the body even when I am having a high dose of vitamin D (DV 60K)? My calcium level is good but why I feel bone pain? Why am I having watery stools? I am vitamin D deficient, so do I have cancer?

Kindly help.

Thank you.

Hello,

Welcome to icliniq.com.

Muscle pain or joint pain, and watery stools are among the side effects of vitamin D. These symptoms can also be seen in thyroid problems or diabetes. You have mentioned that your blood reports are fine, but have you been tested for thyroid and diabetes? No, definitely it is not cancer, so relax.

My advice to you is to take vitamin D once in two months instead of monthly once. Get exposed to bright sunlight. Repeat the vitamin D test after two months.

I hope this helps you.

Take care.
