All of your symptoms are definately consistent with candida, but if it is candida, it's perplexing that you would have the same outbreak for 6 years without it spreading or becoming more serious. At least with me, once candida started growing outside of my body, it started spreading down my legs very aggressively. It's definately good that you are seeing an infectious disease doctor about your condition. Hopefully, when he looks at it, he will be able to tell whether it is candida, and if not, what exactly it is and what is causing it. It really would take a doctor with experience dealing with the candida condition to look at it to tell.
Good luck and please let us know when you learn more!
