Today I felt a little better so my father, Lady and I went to Croft Hill for a walk, my intention was a short walk up the old Croft Hill to let dad see the views but we met a nice women with two Labs and ended up walking up the new Croft Hill, down to the nature reserve and back to the car.
Anyway the foot didn't feel uncomfortable even once and I didn't get out of breath so perhaps things are improving. My dad loved the 3 mile walk, it was his first time up there in over 35 years.
