Am I getting pain in arm, hip and knee due to low vitamin D level?

Hi,

Welcome to icliniq.com.

I cannot say it with utmost certainty, but yes it could be due to low vitamin D3 levels. The majority of patients with moderate to mild vitamin D deficiency (serum vitamin D between 15 and 20. The majority of patients with moderate to mild vitamin D deficiency (serum 25[OH]D between 15 and 20 ng/mL [37.5 to 50 nmol/L]) are asymptomatic. Serum calcium, phosphorus, and alkaline phosphatase are typically normal. Serum parathyroid hormone (PTH) levels are elevated in about 40 and 50 percent of patients with serum vitamin D levels less than 20 and 10 ng/mL, respectively.

Patients with low vitamin D and increased PTH (secondary increase) are at increased risk of having rapid bone loss, seen as low bone mineral density (BMD) in dual-energy X-ray absorptiometry [DEXA scans]), fragility fractures. With chronically low vitamin D levels one can develop secondary hyperparathyroidism, which can affect serum calcium and phosphorus levels. The patient usually develops symptoms at this stage with features of osteomalacia (bony pain, etc.). I do not know your vitamin D levels, but there is usually no harm in taking vitamin D supplements orally weekly or daily.
