Im in a lot of pain after surgery on my tybia in my knee is it normal to have swelling in my ankle and foot?

Quite commonly seen: Surgery anywhere on the leg will likely result in some pain, and swelling in the lower area, espcially foot/ankle because these are the lowest parts of body that are influenced by gravity. Surgery disrupts the normal chanels of fluid/blood flow and thus fluid from lower areas has trouble moving up against gravity, thus swelling. Leg elevation helps. If severe pain/swellig, consult doc. Good luck.

Yes: As the tibia is healing from the surgery, it will typically cause swelling from the knee downward. See your surgeon if this becomes worse or painful.

Yes: Not uncommon, elevate your foot, apply ice to the region of surgery and if you are in "a lot of pain", you need to call your surgeon and let him know. Feel better.
