I have discovered stress causes my HS. I did have them a lot when I worked in a job I hated. I left and they cleared. However until this week my last attack was 10 years ago after the death of my father. I have had a great deal of stress lately and "hey presto" HS has returned. I'm trying to stay calm but being in pain doesn't help.
