Just wanted to say take care and try and roll with it.
The normality of what you had prior may not return as the node clearance has upset the nerves and the lymphatic system. My armpit used to feel wet for a long time as well as numb. In time I had a lymphatic drainage massage as the system needs to find new pathways. Ask when you can start using deodorant again, and that is hilarious when it is numb because you are not sure if you have rolled it on or not! Have to laugh!
It will all work out, just the minute details are not always explained until you are in it and wondering, who the, what the!
Everyone here has words of wisdom borne through experience, just ask away!
