Vitamin D and multiple joint pain
I am a 41 y/o male and have been having multiple joint pains (wrists, elbows, knees, ankles and now it started in my hands)for about 3months. I also have muscle twitching and my right thumb spasms (tetany) mostly at night. I went to the Rheumatologist who ordered tests for autoimmune disease in particular Lupus(ANA), Sjorgren(SSA_SSB) and RA (RF, anti-CCP) and other inflammatory markers. All blood test came back negative and after physical evaluation of my joints, he said it was not RA (which is what I was suspecting since I also have dry eyes which started 6 months ago).
He told me I didnt have any inflammation, redness, warm joints or evidence of fluid accumulating in the joints. He did agree to run a vitamin D test which came back at 18. He said my symptoms may or may not be a result of my low D levels. I am really confused because I have been taking 50,000 IUs vitamin D weekly along with 10,000IU daily with 600mg Magnesium Glycinate for three weeks already but I have not felt any improvement so far. Could all these symptoms be related to the D deficiency of could it be something else? Also, how long would it take for the Vit D and the magnesium take to start showing results?
Im starting to feel like this is not going to end. I have read that sometimes, specially in early autoimmune disease, the test will come back negative. I have also read that some people with Vit D deficiency have symptoms similar to mine but I dont know if my deficiency is low enough to cause general joint pain with no inflammation. Please let me know what you think.
