I had turbinate reduction surgery three days ago - is the following normal?

I am experiencing an unusual (for me) but enduring headache and pressure, from behind the nose, above and behind the eyes and pressure and pain inside the ears. (Also, for several hours after the procedure, if I leaned over to pick up something off the floor, I would get an intense pressure in the head and nose bleeds.) Is any of this normal? Did I cause damage by leaning over after the procedure? Symptoms aside, when is it ok to weight lift, be in the sun, or play non-contact sports? Thank you!
