Hi there, all of your symptoms, except perhaps the fungal infection could be related to a vitamin B12 deficiency. 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. 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. Doctors don't understand B12 deficiencies at all and blood serum B12 tests are pretty hopeless (some people have lots in the blood but can't methylate it (get it into their cells). All the best.
