What Could Cause Severe Sweating During Any Activity, Have History Of Multiple Operations?

I am having a problem with heavy sweating. I am a female and 68 yrs of age. Every time is use my arms to fold laundry, chop veggies for dinner, clean off the table etc I begin to sweat to the point of it dripping off my nose, also walking at any speed other than turtle slow. I can not enjoy eating dinner because I get so over heated. Last year I had a very bad bone infection in my right leg, at the knee and down my tibia, hardware was removed from my leg which had been inserted when in Sept. 2009, i broke my tibia, fibula, and knee, had compartment syndrome. I have had several operations on my leg from 2009 up to last year. My internist seems to think that my body is reacting to pain from my leg and back as I do not stand correctly and my walking gait is incorrect due to my problems with my leg. I m beginning to wonder if there might be another reason that we should be looking for. My Mother died of a masdive heart attach at the age of 55. I am the only surviving member of my family (mother, father, two older brothers). Thank You
