Hi
Have you tried a full body cleanse. parasite cleanse, Liver Flushes and colon cleases. Drnatura has great products. I ordered my initial parasite cleanse from drclarksstore.com.
I also use a zapper and it kills everything. Try zapping everyday plus oral parasite killing herbs. If it is candida....they live on sugar....cut ALL sugar, carbs out of diet while cleansing.
