Is it okay if I ask some questions via the hospital's KakaoTalk?

After going to Daum for a consultation, I actually ended up having even more questions.

Before the consultation, I even took notes, thinking I would ask everything imaginable.

But once I actually went in, I was nervous and too busy trying to understand the explanations to actually ask a few of the things I intended to ask.

The director personally explained the design and asked a lot about the things I was worried about, but thinking about it now that I'm home, I have more questions regarding the recovery period.

When can I start exercising after the surgery?

How fast does the swelling go down?

Can the areas I'm concerned about actually improve as much as I want?

I thought I understood everything during the consultation, but as I looked through reviews again at home, I keep thinking, "Why didn't I ask this?"

So I'm debating whether I should ask them via the hospital's KakaoTalk, but is it okay to ask these kinds of things?

I'm worried that they might get annoyed if I keep asking trivial questions after I just went through the consultation.

Did everyone else ask the hospital via KakaoTalk if they had questions after their consultation? Or, since I've already decided to have the surgery anyway, should I ask before the surgery?
