Do you walk with a single crutch or a stick? It is important that you are using your crutch correctly to help stabilise your balance, and reduce risk of asymmetry through the legs, hips and lower back as this may lead to further problems or injuries.
As shown in my video, the most important step is that the crutch goes in the OPPOSITE HAND to the injured/weakened side. This helps maintain a normal walking pattern and reduce the risk of imbalance. The second step is to put the crutch down at the same time as your injured side. This will help you balance out your weight more evenly and help reduce your limp.
Have a look at my video to see for yourself the difference, and check whether you are doing it correctly
