Recently diagnosed with HS. Should I have a secondary consultation ?

Thank you for your time I taking to read this. I (29m) started having these lesions under my arm. I first attributed them to heat boils and thought they will go away. There were a few of them. Most of them went away except for one which kept coming back.

Went to my family doctor, who took one look at it and said it was HS. Was prescribed antibiotics and then a cream. Both haven't worked so far. I think I have a new between my butt cheeks now. At this point, I am hoping this is early stage and I can deal with this quickly. Should I ask for a derm referral?

Also, is there a chance this could be something else? I am just worried reading the posts in this sub.
