Is it possible that local anaesthetic doesn't work for me?

Hello,Yes, it is possible, though rare that a patient would require as much medication as you describe after standard breast augmentation. I recommend that you continue to follow up closely with your plastic surgeon to ensure that you have adequate pain control.All the best

It is possible for some patients to be somewhat more resistant to local anesthetics.  Patients will often figure this out after dental procedures when they require higher doses of local anesthetic.  There have been some studies, mostly in the dental literature, that indicate that patients who have red hair have a higher incidence of resistant to local anesthetics.  While breast augmentation can cause some discomfort after the procedure, the pain is typically not so severe that it requires morphine. Hopefully your pain has improved. Some patients who have had submuscular implant placement benefit from oral Valium. This medication can reduce some of the muscle spasms that can sometimes cause pain.  This wishes to you!

It is possible to be resistant to local anesthesia. A good way to determine if you are truly resistant is if you have had any dental work that required the use of local anesthesia.
