And...Can Sciatica cause numbness in my right leg?

I’m not thinking about just when it falls asleep, I mean when I sit, stand, walk, etc a certain way i can make my right leg go numb. Is this normal? When I asked my doctor he kinda deflected the question and changed the subject and then time was up so I didn’t ask. My leg goes numb the most when I bend over to do things like scoop the cat box, pick things up, etc.
