Not yet. Received AOR Mar 20th

Did my medicals Feb 14 and received medical furtherance Mar 04, CIC wants me to do a repeat X-ray and also asked for an additional medical report from my doctor in regards to my Medical condition.
My questions are:
1. Have you seen cases of people with lupus on this platform and how their application went. I am really worried about whether this will lead to Medical inadmissibility
2. Is the application always put on hold until medical clears or do they proceed reviewing documents while they wait for the additional reports?
Thanks.
