2 or 3 months ago I noticed a red dot / mosquito like bump on my left butt cheek. Pretty low and easier to see if you pull the cheek out a little. That was 2 or 3. Months ago, last week I was telling my husband about it, because I believed it had gotten a little bigger. It never has itched or bothered me. Within 2 days of telling my husband about it, this thing seemed to have grown to the size of a large marble. It's hard, has no opening, it's looks like a bruise, (oval), it hurts to pinch in pressure it. Today, it hurt to sit down. Calling for appointment in morning. I'm 54 years young, very active with animals. (dogs). Not a sitter. Pretty healthy.

Anyone else have this.?
