When I was drinking hot water half of my tongue got burned so I took a glass to drink normal water. And after drinking the water I noticed something like blood on the inner side of the glass which I used to drink water after my tongue got burned. I drank two times from the glass. And I did not rinse my mouth too after drinking the water because I noticed it next day morning because I drank the hot water at night and then drank from the glass with blood when my tongue got burned. And my tongue was burning and there were small blisters and like cracks present on the tongue when I drank the water with blood. The blisters or cracks aren't painful but when I touch my tongue it's burning. So can the blood go inside through these wounds? Are the cracks present on the tongue caused by hot water and are they open wounds? Because we have cracks on our tongue normally. And I am scared of hiv or hep. Can the blood go inside my tongue which is burnt because I drank hot water and I didn't rinse my mouth or tongue too after drinking from the glass with blood and also I drank as soon as after 5 to 10 minutes after my tongue was burned from the glass with blood. And the blisters are not that big. My main concern is that is it a open wound because my tongue was burning when I drank the water. Is this a open wound to allow hiv or hep? I am really worried.
