Why does my nose burn after I use nasal spray?

Do you use it a lot? Or have you used it for more then 3 days?

If you have it's probably because the lining in your nose is irritated by the over use.

I would suggest taking a break from it, even if you haven't over used it.

Try Saline nasal spray, it should help. I would try 4-Way Saline nasal spray, expessially

If you have been over using, it really helps for the over use of decongestant sprays.

However, if you haven't been using it for more then 3 days or using it too often, I would ask your doctor, and either way, lay off the nasal spray, it may be really damaging your nose.
