Thank you for submitting your question.
Kenalog celestone injections should not lead to swelling. Kenalog is a steroid which helps to decrease inflammation and swelling.
If swelling occurs after a kenalog injection, then infection is a possibility. Any time the skin is penetrated by a needle, there is a possibility of bacterial entry and infection. Infection is especially likely if the swollen area is red and hot.
I hope this answers your question.
If the area is not warm/red, then it is possible that the kenalog+lidcocaine mixture got into those areas. This should resolve within 1-2 days. You can apply warm compresses to the area to speed up the process.
If the area is red and hot, then you may have a skin infection.
If the numbness has persisted for 2 months, it is likely that the a branch of the facial nerve was punctured/damaged during the injection.
Recovery from nerve damage can take up to 4 months. Numbness is the most common symptom. Mild swelling is possible, but your face should not be grossly swollen from a nerve injury.
That is very odd indeed. It's hard to imagine why the kenalog would travel up to the tip of your nose. If you have taken antibiotics already then infection is unlikely. You may need another visit back to your dermatologist if this doesn't resolve.
