Reply To: Hello, I have been diagnosed with Vitamin D deficiency in June 2015 with level of 23. While taking the Vitamin D 5,000 I was experiencing muscle pain and bone pain. I just got my level checked again because the pain and weakness of muscles and bones cracking and tightness has not improved and now my Vitamin D level is – Vitamin D, 25-Hydrox 67.4 ng/mL While this is a good thing it went up, my symptoms just do not seem to improve. I am taking a Multi vitamin as well as Magnesium and Calcium supplements as well. Any help or suggestions? I have had so much blood work done and everything came out negative. But I my muscles feel week and bones still hurt.
