Hello and thanks for posting

I am sorry to hear about your recent surgery and the nerve damage you are experiencing since.

The nerves are commonly interfered with during this type of surgery and many patients will have experienced the same as you. As you say this usually improves with time and certainly exercising and keeping the arm moving will help to ease this and regain it's strength.

Try and take things one step at a time, it is still early days but do ask the physio questions and see what else they can suggest to help.

Best wishes

Naomi
