What Causes Tiredness And Creamy White Discharge From Navel In A Gluten Allergic Person?

All my life iv been eating pretty much anything and recently found out im allergic to dairy and gluten. Im 28yrs oldand have found it a tad of a struggle but im doing and coping ok with the changes. Only since the dietry changes I feel run down im feel tired alot more easily and my belly button has developed a creamy/white smelly discharge that leaks out, sometimes it becomes very red itchy and rather painful too. Wht is this happening and what can I do to stop it? At times iv also suffered with what I call fanny bogeys its like a white ish looking... Well bogey but between my lips down there. Iv been tested and I have no std or sti so I dont know what whst this is, im very clean shower orbath everyday. Please help
