My 48 year old wife who has had bilateral mastectomies with autologous reconstruction in the last 2 years, is now having a great deal of fatigue and some tingling in her hands and feet. She also complains that her legs often feel weak and achy. First surgery was in May of 2014 TRAM flap, and her second surgery was bilateral TUG flaps in December of 2014. She was septic after the second surgery and was rehospitalized with a severe allergic reaction to Bactrim. Could this be a delayed after effect of the surgeries or the start of something more ominous like MS?
