Bone & Muscle problems

I am having pain while folding my legs or while walking fast. I recently did a executive  test which shows vitamin d3 deficiency. My level was 5. Could this be the reason for the Pain in my knees? Please advise what medication I should take?

I am suffering from pain in my feet, specially at the heel area and if I walk fast or a bit more than normal, they hurt immensely. Also, from past 2 days, I am not even able to stand properly because of the immense pain in the heel area of my feets.

Banged the ankle onto the heavyweight rod . Kept ice immediately. But there's pain and swelling now. Could it be a fracture? Wt first aid can be given immediately?

My son was not able to stand on his feet and his right leg was not supporting. Post all blood tests, including CPK test our Pediatrician concluded that its a muscle spasm. But my son recently fell off the cot and had his left side bone above eye swollen and blood clotted too. We informed our pediatrician but he mentioned nothing to worry. My question is do I need to see a specialist for this kind of problem. Please suggest. Thank you. CPK reading - 139
