I am a 75 yr old African American female. Retired as of 7/1/16. For several months, I have had a general feeling of extreme weakness, sometimes short of breath...but also experience excessive sweating...at the slightest of activitiy--even making my bed or cooking/doing the dishes, making the bed, folding clothes/linens, etc. I do o all my home chores and errands, etc. but noticed this weakness and excessive sweating when working about house doing daily activities. I have asthma & use CPAC machine, fibromyalgia, osteoarthritis, spinal stenosis and degenerative disc disease and some ankle swelling/soreness---redness below ankles. Have metal plate and screws in a leg that was broken in three places a few years ago My doctor just ordered a stress test. Any other suggestions?
