Hi there, this post is old but I recognised most of your symptoms from a deficiency I also suffered from, vitamin B12, I have just started writing a blog as I have healed myself from this deficiency in early 2016 and I am keen to get the word out there as to the list of symptoms that come with a B12 deficiency as well as the simple cheap cure that I found worked for me. I had difficulty swallowing, hence the name of my blog, but you will find good information contained within. There is also a video there third one down on the research page which specifically speaks about the link to hairloss. You don't need the injections, sublingual methyl B12 works just as well. Since I am new, I can't post my blog link here, but if you are interested try typing in difficulty - swallowing di christian (my name) and you should see a video with a link to my blog. All the best.
