Symptoms: I have a constricted throat. Tongue changing colour to white. The tip of the tongue has red dots on it. The tastebuds are enlagred.Area above the tongue white. Sides of inside of cheeks have small grain like dots on it. Mouth sores are common. I have small sores inside my lips. They appear to Canker sores.

I fear it is an Std. I engaged in oral sex. However I got tested for them and it came back negative. Negative Hiv. Hsv.(igm and igg) Syphillis.

I am quite upset because I dont know what this is.
