I woke up with an abscess on the back side

Patient: I woke up with an abscess on the back side of my upper thigh, just below my butt cheek..I saw a doctor and got it Lanced and drained and packed. I’ve been keeping it covered and clean. My question is: Am I contagious? Are my roommates at risk? Will I get another abscess now that I’ve had one?

Symptoms: Swollen area with wide area of redness.
