Hi, my boyfriend has been complaining that he has limited mobility following a complete lymph node dissection (underarm). He said that it feels like a guitar string (maybe a nerve or a ligament?) was reconnected too tightly. When he raises his arm to a certain point, he experiences a lot of pain and can go no further. We can even feel the "string" from the surface of his skin. It's been just over a month since the surgery. Just wondering if anyone else has experienced this. Thanks.
