Does anyone’s skin get extremely thin and soft after an abscess and then develop ulcers?

I recently had a big abscess develop on my labia majora (never had one develop there, only on my thigh). It thankfully drained itself. It left a crater like area and the skin above the crater like area where the abscess was is extremely thin and soft. It feels velvety almost.

Yesterday it started hurting but it’s not filling back up. Today I noticed there’s an ulcer.

Has this happened to anyone else? Common HS thing? Or is this a separate issue?
