Have a huge sebaceous cyst,, kenalog injected today, I wish she would have just taken it out. What dictates a Kenalog injection, vs excising the cyst? And of course when the pain comes down, I really would like to get what s in there out of there. And of course then get the sack out. Very young, very busy Dr. And she took very little time with me. Measures 4 centimeters. Thank you for your time, Kathee LPN
