Yes, I am 78 years old and have a problem whereby I experience excrutiatin fatigue in both legs after my initial defective Stryker hip sugery. Before I could not walk more than 40 feet and I need to sit down for the fatigue to go away. Now it is 10 feet or less. I use to ride a indorr bic that was low to the ground for 30 minutes with no problem. Likewise I did aqitic in the pool with no pain until I got out of the pool. I have been checked by my back doctor and neurologist and they can find nothing related to cause the above. I even done an EMG test. Any Idea as to what the above is attributed to? Eli DeKasha
