Picking dried blook out of nose after a septoplasty. Is this bad? What are the damages?

It is very normal to have some dried blood in the nose, especially during the first week after surgery. Using nasal saline is a very effective way to rinse out the nose. I would avoid picking the nose because this may exacerbate bleeding. It is a good idea to continue following your doctor's instructions, and if you have any concerns, I recommend making an appointment to visit your surgeon. Good luck!
