I had a partial mastectomy December last year and full auxiliary clearance in July.
Since auxiliary clearance I still have numbness under the arm pit and at the top of my arm.
I did my exercises religiously every morning in the shower and gained quite good movement in my arm.
Then unfortunately I broke my shoulder ( auxiliary clearance side) so I have gone backwards in movement with my affected arm. But I’m working on it to get it back to where it was before the break.
Im currently doing hydrotherapy with a physiotherapist which is helping, plus my exercises .
Slowly getting more movement back again.
As for numbness time will tell, some of my feeling has come back but not all yet, early days though.
Hang in there just persevere with the exercises, swimming I heard is also good.
Sending hugs xx
