Monday early afternoon having a sinus lift and implant placed (molar) by periodontist. local numbing the area. said both can happen together. i was hoping to go to an nba game the next day in the evening. i figure some swelling. is going ill advised?

Not particularly. If you're swollen or in pain you may have to skip the game.

You are facing 2 localized surgical procedures, the operative word being surgical. Treatment will be performed by a highly trained specialist with superlative training and years of experience. Swelling and discomfort should therefore be minimal. Anesthetics & post treatment medicines (perhaps antibiotics, analgesics, anti-inflammatories) may impair driving. If you go, let someone else drive.
