I'm not surprised that you still have pain and swelling. 11 days isn't very long and it takes a long time to get back to normal after this surgery. You mention being on crutches and taking some spills. Do you have either a knee or seated scooter? Mine was a lifesaver for me and well worth the money! Even after I was able to be weight bearing and discarded the crutches, I find that I take my scooter if I am going to the grocery or the mall as it gives me much greater mobility.
Good luck at the doctor's appointment! Let us know how it goes!
