No need to apologise frederick - you're in very good company! Just a few of my syptoms (past and present)are hives, coated tongue, hives, hair loss, chronic fatigue, brain fog, DEPRESSION, thrush, bloating and food allergies /sensitivities (I think that's all!) They are all related (don't let anyone tell you they're not!) The best thing is to get a person (whether doctor or not) to help who has experience with yeast infections (not just read about them) candida can mimic many ailments - that's why people find their doctor's trying to treat the symptom not the cause! You can definitely be free of this (there are people on this forum who have had great success treating it naturally!) I don't know specifically what to tell you to ask your doctor to test you for (I'm not a doctor, this is only my own advice/opinion - but what i do know is that there are hundereds of yeast species and over 8 specific candida species, but it is very likely your doctor will test for less than 4! - no wonder they come up negative!!) If you have the energy - I would take this into your own hands, get some good books etc. I'm goona look for some of my most helpful websites for you now...............
