Lymphedema occurs in about 15 to 30% of patients following breast cancer treatment, and usually presents with swelling of the arm/hand on the same side as the breast cancer. Some women also complain of a heavy, "aching" sensation of the affected limb.
Pain or tingling in the upper-inner arm, and sometimes in the armpit area too, often results from the surgical removal (or injury) of the sensory nerves within the armpit area where the axillary lymph nodes are removed.
