This is hard for me to put in words but do any of you feel like you have lost your staying power, your muscle mass. I 56 years old and used to climb power poles for a living and it was nothing to climb 10 or 15 poles in a day, these poles ranged in height from 35 and 40 feet. Now there were days when we’d have to climb some transmission pole and they’d run around 65 to 80 feet. Hell to see me now trying to walk up a couple flights of stairs; it feels like I’m carrying a couple 100 pound sack of feed on my back. If I use my hands and arms for very long they will start to cramp up and I’ll have to stop and try to shake it off. I don’t smoke and I’m only about 30 pounds over weight but I get so winded these days. I’ve had a stress test, thing it could be something with my heart but that came back just fine. I’m losing my strength and it is starting to really worry me. Have any of you had anything like this.
