I think its the first time Im using it after surgery, but it might take a while for my senses to fully return! Its not perfect, but I still dont know if its a foreign body feeling or a sensation. There wasnt much at the beginning of the operation, but it seems to be coming back a lot... I also had rhinitis and touched the tip of my nose, so its best that the rhinitis is gone. I dont have to touch it anymore and of course its good, but its good that it goes away with the rhinitis... It seems to have passed really comfortably during the changing seasons in spring.. ㅠㅠ It seems to settle well as time goes by and its so good.
