@alaethia- do you know exactly what you had done?
I’m assuming you have had follow up appts and they’ve told you you healed fine? It can be structural/nerve related.
If you push up from the outside of the front of nose do you get a relief of pain? There are many nerve endings that run through the cartilage/bone of the nose. The surgeon has to be very skilled to remove cartilage/bone without weakening the overall structure. Have you asked the surgeon to check for septal perforation? A weakening to the structure of the cartilage and mucosa that covers it, can cause a leaning type flapping affect upon inhilation.
The nasal septum, weather having breathing issues or not, is a strong support system to the nasal cavity. A change to this, even to improve breathing, can weaken the original structure, causing pain upon the new airflow dynamic breathing.
Your ENT or surgeon, would most likely refer you to a Neuro as they don’t treat pain, even if it is caused by them. They will tell you 4-5 months is to soon to tell and tell you to be patient. You know your body and how you feel. Don’t let them make you think it’s all in your head.
Many people experience this pain as a result of septum/bone surgery. They will most likely prescribe you Gabapentin.
