Oral yeast infection symptoms and conditions

I've been on Advair 500/50 for about five years now. Nothing seemed to control my adult onset asthma before then. Singulair worked great but caused shin pain. I seem to tolerate the Advair well in most regards. About 3-4 years ago, I started having a productive cough. It is not all day long, but usually upon first rising and occasional bouts during the evening. I am also hoarse, but it could be due to other meds. I have had pulmonary workup which was great. I have recent cardiac workup, also great. Breathing is fine, better than ever. It is this cough that makes me sound worse than tv's Felix Unger. I am beginning to think it is caused by the Advair, as no other diagnosis is forthcoming.

After reading the first page of posts, I realize I am very lucky that some of the worse side effects. The first time I was prescribed Levaquin, 500 mg. for a UTI, I noticed that after one day my tongue tingled. The second day of treatment left me with a very sore tongue, as if someone had rubbed it with sandpaper. The next day, I got several large white blisters in the roof of my mouth, under my tongue and in the back of my throat. None of these symptoms were listed in the information pamphlet from the pharmacy. I called my doctor and he said it must have given my an oral yeast infection. He called in a prescriptin for Diflucan and Nystatin (an awful tasting orange liquid you have to swish in your mouth and swallow). It did not help. I went to him again so he could look at my mouth in person and I had lost 9 pounds in 6 days! I could not even stand to eat chicken noodle soup and I was living on water and jello. I am a diabetic who has to inject insulin, so my blood sugars were going crazy. He prescribed some other mouthwash and it took almost a whole week after finishing the Levaquin for all the blisters to get to a point where I could even brush my teeth again. I can't begin to describe the pain. I have UTI's a lot, but I made him promise never to prescribe Levaquin again. Well, two months ago, I got another UTI and tried 2 other meds that did not clear it up. He once again prescribed Levaquin, and now my mouth is inflamed and blistered. I don't think it is an oral yeast infection, because the symptoms are not the same. It feels more like some kind of chemical burn. Has anyone else had these symptoms? I just came back from a family reunion and I was miserable the whole time I was there.

I was just diagnosed with Crohns 7 days ago. They started me on 125 mg of Prednisone for 2 days over IV and now 60 mg a day. So 20 mg 3 times daily. I'm severely tired but I think that is just from being in the hospital for 2 weeks and not being able to sleep and I am just now getting home. The main problem is after I started the steroid I have all this white stuff in my mouth. Like the plaque you get on your tongue but it is all over my tonsils, cheeks, back of my throat and my mouth feels really raw. I cant eat because everything burns. The GI siad to gargle with mouth wash but nothing is working. Is the thrush from the high dose of steroids? or because now I have no immune system so I have a yeast infection in my mouth??? Any help would be great. Has anyone notice rapid weight gain with in the first couple of days of being on th ehigh dose????
