I’m sorry too that you’re having a rough time recovering; as you’re still swollen as @Isaiah_40_31 says keep icing, sleeping propped up & maybe try asking for steroids…some members have done massage for lymphatic drainage when swelling’s a problem, so maybe have a look at this:

The lip palsy does take time to recover, I’m sure it’s really frustrating but hang in there…my aunt had surgery for her Trigeminal Nerve Neuralgia, so the nerves in her face were damaged, she struggled to eat & had an eye affected too, it was a big shock as she hadn’t been expecting it & was very down after her surgery but it all healed within a few months- very difficult time but keep strong
