Assalam O Alikum & Welcome to the Forum,
In my opinion you should wait for at least 30 days for the reply of email. And lets suppose if you don't get any reply then the best option will be to apply for GCMS Notes. These notes will give you true picture about your immigration case.
And About Re-Medical Request. CHC ISB sends email to principle applicant these days. And after few days the letter from CIC comes through Registered Pakistan Post. So keep on checking your emails & Mailbox as well.
And don't panic, we (all the forum members) are in the same boat. In sha Allah every thing will be fine soon for all of us (aameen) so don't lose hope
