I'm 17 days post op. The large amount of swelling on my bridge area has gradually improved. I've been conscientious, eating a low salt diet, taping at night, sleeping upright, etc. Yesterday morning I found my nose very puffy again - I had thus far been retaining the more swelling on the right side of the bridge/cheek, now the left is worse! My period started yesterday (a week late, delayed I believe by the antibiotics). Can menstruation cause swelling to return?
