Help

I am so happy to have found this site- at 56 I thought I was the only one in the world struggling with this compulsion. I have a question--I picked a spot on my chin very badly trying to get out an in grown hair. Anyway it is finally starting to heal after many weeks but it is still so sore even though I have also been taking antibiotics because I figured it was just infected. I just want to make it through a day without feeling my face throb. Why is it still so sore and how long will it take for that to stop? Do you think I have damaged a nerve?
