1 day post Restylane injections to my lips with swelling. My lips are enourmous- when should I panic? (photos)

We routinely prescribe a medrol dose pack when patients have a hyaluronic acid filler (Juvederm and Restylane), because flash swelling can occur (albeit infrequently).  This can be dealt with fairly expeditiously by calling your Doctor.

Thank you for your question. It is very common for the lips to look
over corrected or fake the next day. This is due to all the swelling
that ensues. I often tell my patients that this
is the "oh my gosh" day. It can be 'oh my gosh' my lips are so
swollen! It could also be 'oh my gosh' I love my lips even more than
yesterday. Either way, the swelling may last a few days with every day
showing a decrease
in swelling. The more you ice the first day or two, the less swelling
you will have. I would wait a few days to a week and then return to
your injector if you still have concerns after that. If you like the
look of the lips at some point during the swelling reduction, then take a
picture. This way you know what volume you like in the lips for the
future.

You need to be evaluated at the clinic where you had the procedure.  If it is determined you have no allergy and the lips remain too large after a period of time, you can have the filler broken down with hyaluronidase.  It is best to have a hyaluronidase allergy test before treatment.
