Ankle and Foot

I am a 64 year old walker.
Would like to walk 2 to 3 hours.
Because of feet and ankles should only walk 1 hour.
Tend to have cramps in instep.
Cuboid bone is sometimes intensely painful.
Large tendon on the front of ankle swollen.
Two little pocket of swelling on the outside around the ankle bone.
In the morning heels hurt.
Walking is difficult.
Better later.
I remember turning this ankle a lot when I was a kid.
