I have been having the simular problem my circumvallate papillae & Foliate papillae hveboth swollen for over a year. I was told it was thrush and have been treated three times for thrush have been tested three time for herpes(HSV), siphis,HPV, cancer,liver ,kidneys, HIV i had her test everything all negitive results my doctor said my immune system is low though. I have rinsed with salt water sucked on pieces of garlic, probiotics, vinagar i have tried everything i could!! they well not go away! I smoke about 10 smokes a day i drink coffee constantly with international delight creamers and have noticed that by the second cup my throat starts to hurt or feel irritated of i drink coffee with just milk and sugar it doesnt seem to bother me at all. when i brush my tongue there are little white pieces or tabs of skin on my tongue after. before i brush everyday my tongue has a film some is yellow brownish from smoking and where my circumvallate papillae is where it looks thrush like. I also think the are ulcers in my throat it seem like it my tonsils that hurt and if i stop drinking coffe and switch to jucie pop or water my throat doesnt bother me at all.Its just not going away. I also have had issues with my skin breakout everywhere that according to my doctor may be gluten but it is mostly my lower legs,face(nose),back of upper arms and hips these are bumps dry skin, blood blisters some heal in two day others stay for months i hive when i use expholiating stuff or anything oil of olay(posion) causes me to hive.and it all seem to be some thing to do with my folicals i think. anyway my doctor sent me to a dermy for my skin and she gave me six months precription of NU-DOXYCYCLINE Yes this is the same thing they use for some stds for you that want to jump the gun i well repeat have been tested 3 times in the past year not to mention once a year every year before that. and have had the same partner for the past year who also has nothing cause he was at the doctor about two weeks ago and my last appointment was just this past january. Anyway the NU-DOXYCYCLINE seems to be clearing the skin issues and seemed like it was clearing what is happening in my mouth but it has been a month im on my second month of the meds and it seems like its healing my mouth too but really slowly. i am going back to my doctor agian soon see if she thinks i need more oral thrush meds don t know what else to do I also have noticed fruits like peaches pinnapples and strawberries tend cause me to feel like i am sweating in my t zone mostly right between the eyes where my nose meets up at the forehead don t know if this is connected.
