Slight Bleeding 4 Years After Septoplasty?

Hi I had septoplasty 4 yrs ago.Last year I poked my nose with a qtip a little too high up and the next day there was slight blood in the morning when I cleaned it. Since then for the past year sometimes there is slight blood when I clean my nose and there was no bleeding ever before that. Is there any way a deviated septum can come back? I also feel my nose got bigger like my nostrils and the inside part from the poking, is that possible? I don't drink as much water, does that stop the bleeding.
