What are my options for lowering nostrils? I am unhappy with them. A non surgical option would be ideal, but open to all.

This is something that surgery can improve. While it can be done under straight local anesthesia, most patients will do better with either sedation or general anesthesia. I am not aware of any non-surgical options that would be of use here.

Hello and thank you for your question. Alar batten grafts can be used to lower the nostrils.  Make sure you
specifically look at before and after pictures of real patients who have
had this surgery performed by your surgeon and evaluate their results.  The
most important aspect is to find a surgeon you are comfortable with. I
recommend that you seek consultation with a qualified board-certified plastic
surgeon who can evaluate you in person.
Best wishes and good luck.

Unfortunately, there are no good non-surgical options for lowering the nostrils. You could benefit from alar rim grafts to reduce columellar show and possibly weir excisions to improve flaring. Given that your septum has already been operated on you would likely need an ear cartilage harvest to provide grafting material. While this could technically all be done under local anesthesia you may prefer to go to sleep. Good luck!
