The first few follow-ups were getting the dried blood out of sinus cavities so that was intense for me. He sprayed lidocaine in my nostrils to numbing the areas then used the tiny camera to search for debris. I just closed my eyes and prayed 🙏. 😊. It was a necessary thing to do. After that, the sinus rinses took care of the rest. The Neil Med sinus kits have the spray bottle and some saline packets. One packet along with distilled water to the fill line is easy to do. The sinuses feel so good after I did that.
