Lesa- Yes I had it done in July, back when they were still trying to figure out my problem. They did a CT scan and found an abcess on my lower right side, it wasn't as big or as involved as yours, but they decided to drain it while in the scanner.A radiologist does the procedure. They put you in the CT scanner, give you drugs to relax you and to numb the area. Then when they find the area they want to go in at they insert the needle and drain it. You really have to stay absolutly still, I jumped when they inserted the needle(not enough pain killer)and they had to start over.It went pretty quickly. Good luck-when do you think you'll have it done? Let me know!
