Is it OK to remove the splints/stent 3 or 4 days post septoplasty surgery?

My appointment is on the 7th day to remove but having a lot of problem breathing through my mouth. I think ive caught a cold/flu after the second day. Breathing is getting worse even with the medication. Having a panic attack trying to breath. Called the hospital to book an appointment for earlier date but none was available. What should i do? Getting really scared over breathing during the night. Should i go to the ER and ask to remove the splints? I think im losing it right now....
