Bent over to wash hair 1 month post rhinoplasty. Having pain

I'm one month post rhinoplasty and washed and shampooed my hair bent over in the sink. That would have been a good 15 minutes. After that, I've started to notice having intermittent throbbing pain in my nose and perhaps more swelling. I didn't have this kind of pain before in the weeks prior. Worried that I have injured my nose !!!
