I've had lymph nodes removed and can't have IV, canulae, or BP taken from that arm because he could get Lymphodema,I C&P this bit "Lymphodema is a chronic condition that is caused by a disruption or damage to the normal drainage pattern in the lymph nodes. It most often causes swelling of the arm, but it can also affect the breast, chest, and sometimes even the legs. The swelling, caused by an abnormal collection of too much fluid, is called lymphedema. Removing the axillary lymph nodes increases your risk for developing lymphedema." but I didn't heed the good doctors warning and now have Lymphodema and it's ever so painfull
