Is this just swelling from fillers or do I need to get this dissolved? 4 days post non surgical nose job. Help. (photos)

Swelling can be typical and can last for 1-2 weeks following filler injections. If you're unhappy with your final results, you can have it reversed with hyaluronidase and try a different technique next time. See an expert. Best, Dr. Emer

HA fillers are hydrophilic. That means that they hold onto water. You may be seeing some excessive fullness, only four days after your procedure. If you are concerned via nasal appearance over the next 2 to 3 weeks, you should contact your surgeon. Thank you for this question, and I wish you were moving forward. Sincerely, Dr. Joseph

Thank you for the question and photos. 
You do seem to have more swelling than usual but it is difficult to answer this without knowing what filler or how much was used. 
Either way, you need to wait 2 weeks until you can really say for sure how things will look in the longrun. If you are very concerned then book back in to see your plastic surgeon.
Good luck!
