Cold sores are herpes simplex virus so yes I guess I can come up because your immune system is low from the HS

Blair, Personally I do not get the cold sores with my h.s. flares.

No, never have I gotten cold sores. Been dx since 2019

No cold sores for me so far, but have only had HS for about 15 months.

Agree, viruses tend to appear with low immune system.
