I have frozen shoulder. Also I feel pain at different places of my my arm. During night, it starts hurting at some random location on my arm, in whichever posture I try to sleep. The point of pain goes on shifting with changing the posture. My Vitamin D report says it is 8.6 ng/ml. My doctor prescribed me a dose of 60,000 IU of Vitamin D3 (1 gm cachet) every alternate day for 2 months. I searched the Google for the dose of this medicine. On almost all the sites, the recommended dose is 60,000 IU once per week or per month. Please advise me the correct dose.
