A vitamin D level of 7 ng/mL indicates severe Vitamin D Deficiency, and treatment is necessary. In some cases, doctors may prescribe high-dose vitamin D such as Arachitol Injection or oral vitamin D supplements to quickly raise the levels, but it should only be taken under a doctor?s supervision to ensure the correct dose and avoid excess. A TSH level of 9.2 suggests Hypothyroidism, for which doctors commonly prescribe thyroid hormone replacement such as Levothyroxine. It is important to consult your doctor for proper evaluation and the right dosage, as both vitamin D and thyroid treatment need monitoring with follow-up blood tests.

Rickets is usually caused by vitamin D and calcium deficiency, which can lead to bone pain and difficulty walking. The medicines your doctor prescribed, Shelcal (calcium supplement) and D3 60K (vitamin D), are commonly used to treat this condition. With proper treatment, a balanced diet rich in calcium, adequate sunlight exposure, and regular follow-ups, most children improve well and can recover completely. The pain in the knees and ankles should gradually reduce as the bones become stronger, but it is important to continue the treatment as advised by the doctor.

A very low vitamin D level (6.5 ng/mL) can cause bone pain, muscle weakness, and joint discomfort. In your father's case, the swelling and pain in the knee and ankle may be due to a combination of severe Vitamin D Deficiency and age-related joint wear (degenerative changes), which is often related to Osteoarthritis. Treatment usually includes vitamin D supplementation (often high-dose vitamin D for a few weeks, followed by maintenance doses), calcium if needed, pain-relief medicines, and gentle physiotherapy or exercises to strengthen the joints. Sunlight exposure and a balanced diet also help improve vitamin D levels. If swelling persists, it is best to follow up with the doctor to rule out other causes and adjust treatment accordingly.
