Your symptoms/ health problems could all be related to candida yes. Have you taken a questionnaire?? Do a search on The Yeast Connection Dr. William Crook. Take the questionnaire. I assume that you have taken anti-biotics for many of these illnesses. they are a huge huge factor in causing this and that is what go me into trouble. Also steroid type drugs and birth control pills are culprits. Also you can try the spit test too. First thing in a.m. before putting anything in your mouth spit in to a glass of water. If you see white stringy stuff coming down I think within an hour you most likely have candida. When I spit it takes about a second before the white stuff starts hanging down.
Good luck to you,
Sometimes just getting the proper diagnosis really helps but if candida is what you have it won't be easy to get rid of so get prepared for the long haul.
