Cmason8869 0 Posted December 17, 2015 I've had a huge acne cyst on my cheek for about 2 months now so yesterday I went to my dermatologist and had a cortisone injection. I did my research before and read that I would see results in the same day. I woke up this morning and checked it and it doesn't look like anything has happened? Its still red, inflamed, and huge. Should I be concerned?? Quote Share this post Link to post Share on other sites
CNA7 54 Posted December 17, 2015 (edited) It can take anywhere from 24-48 hours for the cyst to deflate. Hang in there! Edited December 17, 2015 by CNA7 Quote Share this post Link to post Share on other sites
