I had a nasal endoscopy without Lidocaine for rhinitis before seven months. I did not have any side effects after the procedure. However, yesterday, I had another nasal endoscopy with Lidocaine. Now my nose is stuffy, and I have also got a headache, pain inside the nose, and it hurts when I administer Dymista. Is it a normal side effect? Can I keep administering Dymista? Kindly help.
