I'm not sure what the answer is to cording but I am seeing my physio next week to find out. Yet another little detail they neglected to mention before my full axillary lymph node removal. Rare chance of lymphedema in later years was all I was told.
Now I have tendons under my arm tight as drums, it follows through the inside of the elbow where I can feel the same two tight cords and it finishes up in my wrist. I am a leftie and its my left arm so I am totally p..eeved off that every time I reach out for something I get this pulling sensation that says hey watch what your doing and sends some pain just to reinforce it.
