Test your Testosterone as well as all other vitamins. This may be a cause or the cause, the doctors don't know what you feel and can pass it off as nothing. Don't let them, be very proactive, I learned recently men have little options when it comes to this compared to women. Look up the symptoms of low t and see what you think. http://www.healthline.com/health/low-testosterone/warning-signs#Hair5
I thought it was my Vitamin D and other vitamins and it was not.
I'm on my 4th day on the Gel and I feel ABSOLUTELY amazing! My energy is back and I'm enjoying life again.
Have your vitamin D checked!! I had the same problems and found my vitamin D was 8ng/ml in Jan 2015 severely low, should be 50 to 80.
