Welcome to the forum. I suggest you to limit your walks, do not over-strain your legs. Your weight can be a cause of the unstability that you are complaining. You can apply pain-relieving oitment or sprays to feel better. Hot fomentation can help.
Take analgesics and calcium tablets and nerve
supplements to help your nerves and bone get stronger. If still restlessness
persists, report to your treating doctor, you may need immediate attention.
Wrapping for support can be a little helpful temporarily but let the wounds heal properly do not strain them. Take care.
