Yes tinnitus is pretty common when you have candida. As far as I understand it, it is about candida being in your sinus and ear canal. Vitamin C and the spa steam room help a lot on the short term basis. As getting rid of candida will, on the long term.
I went very far until I could get a candida diagnose. My digestion was very bad so I could not absrob essential elements. Even then, the doctors would only come up with an anemia diagnosis (which in their book explained my chronic fatigue).
A few months later I found out about candida, thanks to my brother's chiropractician. It had been some 15 years that I had Sugar
'intolerance symptoms': 15 years of candida. It is a deal to heal but I am almost there. I am lucky I did not loose my job in the process - mainly because I had asked for a very slack schedule so as to finish my Ph.D. I am lucky I could finish it with the brain fog- as a side effect of detox! I actually had to stop detox for a few weeks in order to do the final sprint!
Garlic flush is something you should do sporadically or for a week at the most. Very efficient!
