Welcome to the community. I hope your recovery is going well. Yes, please call your surgeon if you did not get specific post-op instructions.
Your doctor should have provided post-op instructions. Sometimes I forget I tucked those in my purse. But he or she expects you to call with questions. It's okay and they would rather get a call than have you try something you shouldn't.
Once your doctor gives the OK for exercise, you can exercise. Until then, I'd limit it to walking around to get around the house. It takes a while to heal. I was 21 when I had my cyst removal surgery. No way anything good would have come from much more than that a week in. Even after a month, going to walk around campus was still somewhat painful, though doable, and I was in pretty good shape before the surgery. Consult with your surgeon/doctor regarding what your limitations are personally.
