Yes. The swelling and pain is due to the serious nature of a TPF. After a period of NWB various muscles, tendons, and nerve impulses are not used/used differently. Then getting back to weight bearing and walking is another change the body has to deal with.
Ice and elevation is your friend.
Take some time and read the entries on this website by various people who have suffered TPFs. There is comfort in knowing you are not alone in this.
Take care!
