Thanks for your inquiry an you are early in your post-operative course you need to run things by your surgeon. In general, a sore throat can be from the breathing tube or also can "thrush" which is a yeast infection after antibiotics. Please review your symptoms with your surgeon and hope you have a speedy recovery.
Thank you for the question. If you are not nauseous or vomiting, you can advance to a solid diet. It is best to discuss this with your board certified plastic surgeon. Good luck.
If you are not having problems with nausea, you can likely resume eating and drinking. It is always best to ask these questions of your chosen surgeon as recommendations may be different.Kenneth Hughes, MDLos Angeles, CA
