I feel like I'm getting a cold a day before a septorhinoplasty surgery. What do I do? Can I still go under?

You should contact your own surgeon to review your symptoms and see if it's still safe to do the surgery.  

Hello,I recommend contacting your doctor and telling him prior to surgery. Being healthy is a key component to safe healing post rhinoplasty. All the best, Deepak Dugar, MDScarless Rhinoplasty ExpertBeverly Hills, CA 90210

Thank you for sharing your question about your upcoming procedure. If you are getting sick, I recommend contacting your surgeon to discuss your options. Your surgeon can evaluate you and decide whether or not to postpone your procedure. If you truly have a cold, it is best to postpone until you are completely healthy in order to avoid any complications such as infection and delayed healing. In these situations, an ounce of prevention is worth a pound of cure. Please contact your doctor to further discuss your symptoms. Feel better and best of luck with your procedure. 

Don't rely on opinions from strangers on the internet.  Call your surgeon and ask about it.  

If your cold is very severe, there may be good reasons to cancel your surgery but I wouldn't panic. I would carry on taking the medication, lots of fluid and rest and would let your surgeon know what's going on so they can advise you further. If I have patients in this situation, I tend to advise them to attend the hospital on the day of surgery as planned so that we can assess them. Generally speaking it is perfectly safe to go ahead, provided your symptoms are localised to the nose and quite mild. If you have any chest symptoms, shortness of breath or a cough, then you may need to reschedule

Hello and Thanks for the Question. 
This is a difficult question to comment on. This is something that needs to be addressed by your surgeon and anesthesia provider. Remember, safety first. 
Good luck,

If you really are getting a nose cold and this is an elective nasal surgery, you might want to reconsider a schedule change. May be more bleeding and swelling. Not ideal conditions. Plus, you don't want to go through a healing process while you are also sick.

 Your surgeon and anesthesiologist are going to make the determination whether you  a candidate for general anesthesia. Best  to let your operative operative surgeon know ASAP.
