Hi @Flossy - I didn't have the same surgery as you - but it just takes a while for everything to settle down again & the nerves etc to find a new route. Make haste slowly ..... Make sure you keep your pain meds up on a regular basis. Hopefully it will settle down soon.
Do you have a small pillow to help support your arm? It will really help.
My nodes were 'pulled out' (not surgically removed) and I had a really weird feeling under my arm for well over a month before it settled down - just take your time & hopefully it will settle down
All the best xx
