Oh my goodness, you poor thing! I had a pilonidal cyst when I was about 7 1/2 to 8 months pregnant with my first. It was horrible...I couldn't sleep or turn over because my cyst hurt and I had a huge belly. I had to miss class and work because I couldn't drive. I was so miserable. Because I was pregnant, the doctor said he wouldn't remove it unless he had to. He gave me some antibiotics and some strong pain killers that were okay as long as I didn't take too many. The pain killers really helped and after a week or week and a half the cyst opened and finally started draining. It was messy but I had never felt more relief in my life!
So, I haven't had the surgery but I've had the cyst and just wanted to let you know I hope you feel better soon. Please let us know what the doc says.
