Hi, As you got operated recently, it will take some time for you to accomodate , for day to day work.
Here what you need is physiotherapy
, and for that you should not fear of pain, and try to actively do all the movements, with out fear. If you keep the limb inert for fear of pain, it will become stiff, and movement will become impossible. If inspite of movement it is not possible, we can suspect some adhesions.
I to my patient with such symptoms prescribe neurotropic injection, foe 5 consecutive days, and there after periodically .
