Sorry for the delay popcorn. First thing I will notice is a inflammation feeling n the back of my mouth, both on the roof and back of the tongue. I have an upper plate and the inflammation starts right at the rear of it. If you let it go further you will definitely know something is not right. The Clotrimazole discs dissolving in your mouth will relieve the symptoms rather quickly. I have never had to take the whole dose as prescribed. After I started using a Micro Chamber the amount of times dramatically reduced That is your best first step along with rinsing your mouth out after using the inhalers that seem to cause this problem. I hope this gives you some information you can use. I've been on oxygen over ten years now and have got many answers here, I know you have been around for quite a while also and I'm sure you have got a lot of help out here also. Have a good day popcorn, Dick
