Common Symptoms of Vitamin D Deficiency
Vitamin D deficiency can cause a range of symptoms, many of which are subtle or nonspecific. The most frequently reported symptoms include musculoskeletal pain, such as symmetric low back pain, muscle aches, and throbbing bone pain, especially when pressure is applied to the sternum or tibia. Muscle weakness, particularly in the proximal muscles, is also common. Some individuals may experience fatigue and depression, including seasonal depression, as well as symptoms similar to fibromyalgia, such as widespread pain and discomfort 1238.
Bone and Muscle-Related Symptoms
A hallmark of vitamin D deficiency is bone pain and muscle weakness. In adults, this can manifest as generalized bone aches and pains, muscle pain, and muscle weakness. These symptoms are often subtle and may be mistaken for other conditions. In severe cases, vitamin D deficiency can lead to osteomalacia in adults, which is characterized by bone pain and tenderness, especially when pressure is applied to certain bones 23.
Symptoms in Children: Rickets and Growth Issues
In children, vitamin D deficiency can cause rickets, a condition marked by soft or deformed bones, bow-legged appearance, bone pain (often in the legs), muscle pain, and muscle weakness. Other symptoms in children include poor growth (with height more affected than weight), delayed teething, irritability, increased susceptibility to infections, and, in severe cases, breathing difficulties due to weak chest muscles and a soft rib cage. Severe deficiency can also cause hypocalcemia, leading to muscle cramps, seizures, and, rarely, heart muscle weakness (cardiomyopathy) 4567.
Non-Skeletal Symptoms and Other Manifestations
Vitamin D deficiency has also been linked to symptoms such as emotional instability, frequent crying, anxiety, poor sleep quality, and increased risk of infections in young children. In adults, it may contribute to fatigue, depression, and, in some cases, more severe symptoms in those with underlying health conditions, such as advanced cancer 168.
Eye and Autoimmune Symptoms
Recent research has found that vitamin D deficiency is associated with more severe dry eye symptoms, including shorter tear breakup time, lower tear production, and higher discomfort scores. It is also linked to increased severity in autoimmune conditions like primary Sjögren's syndrome .
Conclusion
Vitamin D deficiency can present with a wide variety of symptoms, most commonly involving bone and muscle pain, muscle weakness, fatigue, and mood changes in adults, and rickets, growth delays, and irritability in children. Many symptoms are subtle and can be mistaken for other conditions, making awareness and appropriate testing important for early detection and treatment 1234+5 MORE.

Cholecalciferol treatment showed mild short-term improvement in fibromyalgia impact scores but not significant improvement in most musculoskeletal symptoms or daily living activities.
