Post Mastectomy Pain

Nerve pain from the damage that happens during surgery can be quite intense from sharp searing pain to pins and needles or throbbing and can take a long time to settle down.  I felt like I had blistered under my arm and on my side but the skin wasn't even pink.  However, tightness can also be caused by cording and that is something completely different which should be treated by a physio experienced in this.  I also had this and while stretching was good, it didn't get rid of it and it continued to get worse until treated.  Cording often runs down from under the arm towards the wrist but can occur on the chest wall and ribs as well.  It is characterised by tightness in sensation and movement and if in the arm, you may be able to see the cords standing out when you try to stretch but I don't know what it looks like on the chest wall.  Your profile doesn't show your region but I'm sure that someone would be able to suggest someone local who specialises in diagnosing and treating this.
