Hi, Dear Dr. and/ or Nurse: I have a terrible time getting a deep breath, but lungs are healthy, doc says, I have no energy or strength in mainly my back and legs and arms also. I can t say a whole sentence without it difficult to breathe; and can t stand for a very long time and can t hardly lift anymore. I m 46, female, mom to a 3 yr. old and married. What is wrong with me?? I don t even have the strength or breath to take a shower. Thank you for your attention, getting a little worried. Been this way for several months now.
