Pre-workout Supplements After Nose Surgery?

I had septoplasty, rhinoplasty and turbinectomy all at once a few weeks ago. I remember reading a few pre workout supplement labels that say not to use the product up to 2 weeks prior to any kind of surgery, so I made sure not to. Im 3 weeks post-op and I'm not really sure if I should go back to taking any kind of pre workout supplement now since im still healing and have lots of swelling left. Would any of you doctors allow your patients to do so or not? Thanks!
