Oh my can I tell you about thrush...Ron has it and bad, still, he was in so much pain last night he was yelling at me, I was this close to just taking him to emergency and this was 10pm last night, PLUS I have it also! I contracted it from him, I've been on Nystatin since 1/19 and it's still there, the burn is the worse. Ron has asked me to call his doc today, because his system is so compromised AND he don't take care of himself like I tell him to, he has taken Nystatin AND the diflucan and it is still bad. I wish they could put him in the hospital so he can't smoke or drink his damn beer WHICH I have told him keeps the thrush from healing but he keeps arguing with me it don't. I am going to call ENT and see what they say to do, I'd rather he go see him but he don't want to drive 45 mins to see him, he wants to go 10 mins down the road to see the Internal Meds doc but I am calling ENT first. He also didn't get the Magic Mouthwash cuz it cost to much. Would this help the thrush? If so he better cough up the money to get it. I can't take this with him anymore and believe me I know this shit is bad and does make you angry cuz of the pain and infection going thru your body you just do not feel good at all! I am finally feeling better with not being drained and tired like I was before I couldn't stay up past 730PM and slept and didn't want to wake up either for work after sleeping all those hours. Now I don't feel tired when its time for bed and I force myself to sleep. From one extreme to the other. And I read NOT to eat yogurt somewhere well it says eating unsweetened yougurt. Says stay away from Beer, Wine, Breads, smoking. And also if you have dentures, which I do and in my 30 yrs of having them NEVER EVER had thrush...but thank God I read about thrush on the internet and it said to take out dentures every night and soak them in cleaning solution which I never have taken out my dentures at night(now I feel like my grandma! lol)and it's been helping. So compromised system from cancer is another factor. Good Luck, with this I can say I know how you feel and what you are going thru and it is NOT fun at all!
