I've never had any problems with my sinuses until I got on nexplanon. Always had allergies but nothing Benadryl couldn't take care of. A few months into nexplanon I was hospitalized due to pain & numbing in the face, also chronic nose bleeds. The doctors diagnosed me with sinusitis & gave me some Zyrtecs & nasal sprays. I had nexplanon removed 5 days ago & my sinuses started acting up again! Has anybody else had this happen to them while on nexplanon? Also, my bleeding after the implant was light at first but last night I started cramping badly with heavy blood. How long did it take your body to go back to normal after the implant?
