Having an active recurrent genital herpes outbreak. Im on Valtrex. Can I still proceed with my Breast Augmentation surgery?

To be perfectly safe it is my opinion that you should have your breast augmentation when you are clear of on ongoing heretic lesion. The surgery should be performed with antibiotic and antiviral coverage. This is the safest merhod for you. 

You need to discuss this with your surgeon and anesthesiologist.  Likely it will be fine but definitely check with them.
