I’ve woken up with a big red pimple the morning of an event – is there anything I can do?

I would not suggest squeezing or trying to remove it. This could just result in a bigger problem.

I would rather recommend that you cover it with a good cover make-up, or if it is causing you pain see if you can quickly pop in to see a therapist who is trained to do safe extraction and cover it with a anti-inflammatory treatment foundation, such as Lycogel.
