I need help with my digestive problems!!

Hi all, firstly thanks for reading and taking your time to read this. So ive had digestive problems since about 18 (21 now) and its getting much much worse. I found out that i had mild candida july 2013 and treated it with a 72 day plan with a nutritionist on a paelo diet and antifungals etc. athough this did cure a lot of my problems such as fatigue, blocked sinus and stomach problems. I went back to a normal diet a bit to quickly and all hell broke loose. 1 week later i started burping like crazy and it smelt just like the food was sat in my stomach, Hair loss from all over my body mostly my head ive lost about 80% of my hair and i want to stop this before it all goes! my head is so itchy and full of dandruff and gets greasy within a day! (note ive had perfect hair all my life never dandruff or any sort of problems), rashes on my face and hands, I flare up in the cheeks so randomly and its like a burning sensation, my bowels smell like death. Ive spent alot of money on supplements and nutritionists and im at a loss. Ive not stuck to anydiet since the one on july which i know is stupid as it worked but i just have no hope. Any advice would be amazing. Thanks you Tweet
