Not sure where to post this, but have you ever had joint pain that is associated with low progesterone? I have been to several specialists for joint pain and other symptoms. They always start out thinking its lupus, then after lots of testing determine its rheumatoid arthritis, even though my tests are negative. My obgyn recently told me I display symptoms of low progesterone, and I read it can cause joint pain. Have you ever had or know low progesterone to cause joint pain flares? Not at a certian time each cycle, but randomly?
