You need to get checked out immediately. You should call your doctor ASAP to schedule an appointment, as several things in your letter concern me. You are only 57, but ...
- You are out of breath after walking 50 feet.
- Your legs burn when you walk.
- You are exhausted.
- You are under too much stress.
I am frankly worried that something is going on with your heart. While it is normal for people with emphysema to be short of breath sometimes with exertion, your disease seems to be out of control. The other symptoms you have, like leg burning, can be signs of vascular disease. I am also concerned that you are tired all the time.
Please follow up with your doctor as soon as you can. Good luck!
