Don, the numbness is mostly at the surgical site. That isn't so bothersome but feels weird. The real discomfort (burning and pain) is under my arm, in the armpit, and on the back of my upper arm. I understand that the lymph node surgery causes quite a bit of pain and discomfort in the axilla. It also appears that a "cord" is forming in the armpit so I need to be more aggressive with stretching, which I am unable to do until the drain is removed. Also, the skin above the surgical wound is hypersensitive... even silky fabric sliding across that skin is extremely irritating. That is why the surgical bra is so uncomfortable; it has velcro front closure and really hurts. Thanks for the recommendation but I won't be applying anything to the area unless the surgeon(s) approve it. I think most of this stuff just takes some time to resolve, but I'm worried that radiation will make it worse.
