Reply To: For a few months, I noticed I was having an anxiety/irritability issue that was getting worse over time, which had me eventually taking an anti-anxiety med to even function. A month ago, I also developed foot cramps and severe backache that was different than anything I had ever experienced. All this started off with feeling cognitively confused, disconnected, and forgetful at times. I finally went to the doctor because I felt something was seriously wrong. They tested my vitamin D (among other things, which were fine) and it was at a level 27 ng/ml . I have suffered from depression and anxiety in the past. Is it possible that a level which is not considered very deficient cause more mentally sensitive and hormone sensitive people these kinds of problems? I am now on a supplement and hope all this gets better sooner rather than later. Thank you.
