Hello, I have studied your case. Due to compression of this nerve root there is tingling numbness in your shoulder and neck. For these symptoms analgesic and neurotropic medication can be started. Till time, avoid lifting weights, Sit with support to back. You can consult physiotherapist for help. Physiotherapy like ultrasound and interferential therapy will give quick relief. For low level of vitD you need supplement or vit D injection. Vit D deficiency is very common worldwide in spite of exposure to sunlight. Vit D is synthesized in liver and kidney so any parenchymal disease of these organs can lead to vit D deficiency. Hope this answers your query. If you have additional questions or follow up queries then please do not hesitate in writing to us. I will be happy to answer your queries. Wishing you good health. Take care
