Hi Susan
I had a similar experieince to your Dad and had to have surgery.
I am now getting mobile again with superb help from the mobile physio, however, I am still wobbly and it is taking time for the strength to come back to my legs. I am only just beginning to use crutches rather than a zimmer, for some of the time. This is ten weeks post op.
I am practising getting upstairs, one at a time, and coming down, gengerly, backwards. I hope to sleep upstairs again soon.
I find that setting myself goals, with the physio is helping.
Best wishes to your Dad and to you. There is so much to get your head round, isn't there. I am awaiting Radiotherepy,
Mavis
