I am not sure what topic to address my inquiry in but I need some help. This morning, I was checking my mouth when I saw two blood looking spots or something like them near the corner of my inside cheek meeting the mouth. I also have been dealing with a white looking spot on the inner cheek, located in the upper lip area. I scrub them out once and a while but after a few days, it would be coming back. I experience dry mouth occasionally and find myself drinking cold water in the middle of the night. It usually occurs only at night, never during the day. I am wondering if anyone has any insight as to what may be happening to me.
