It sounds systemic to me. This means that the candida is everywhere in your body. You’re going to need to change your entire diet, and don’t plan to get back to the sugar again. A medical doctor will prescribe anti-candida medication. The side effects of this medication is not fun, and you can feel pretty awful until your body can process the dead yeast.
It’s effective, but also can be pretty hard on liver or kidneys. It’s important to drink LOTS of water during treatment. http://www.patient.co.uk/doctor/antifungal-medications
An alternative to prescription medication is herbal treatment (you really need the help of a master herbalist, naturopath, or the like) for this. Don’t try it on your own. It takes far longer to accomplish the same goal, but it isn’t as hard on your system either.
With either treatment, you’ll have to drink lots of water, and follow a strict anti-candida diet. Don’t plan on going back to your sugar loving ways, or it can all come back.
People who kick the candida grip on their lives feel much better. I know. I’ve done it.
