I had to wait 4 months to see a doctor for my uLMS, and I personally know of several others now with worse conditions that also had to wait months. If you search around online you will also find many more similar occurrences. Same for ER visits taking literally all day long.
In general I don't think it is a lie, this IS happening.
How much it goes on, or how often it might be a made up occurrence, and how often that needs to happen for you to consider it a "lie", might be a separate matter.
It was 4 months wait for myself but I have seen similar threads for people that had to wait 6.
