I exhale bad odour from my mouth and nose. I even discover whitish substance on my tongue which if I scrape it with brush it will come back in a matter of hours. A jelly like substance also grows on my cheeks. At first, I thought it was an HIV infection but I discovered it was not because I have tested negative three times. I have lived with it for five years now and this thing is causing me a lot of embarrassment. I find it difficult to talk in public. Please help me

The white is thrush and is easily treatable. I don't know what the jelly like substance is, but it might be from an infected tooth or teeth. The odor is probably from gum disease or cavitities, or both. You must see a dentist.
