So sorry to hear you have been struggling but the mental seachange to think of your Walker as your afriend is huge… I feel the same way about my crutches. I know I can manage without them but they are helping me relearn the proper way of walking and form with no risk of waddling, stooping etc.
Re the start-up pain…my physio deceived this as “warming the engine” on a cold morning .. stand up straight. Engage core muscles, clenchbutticks and Walk! Small steps heel to toe and then slightly increase stride.
I walk around on the grass in our garden as well as on the concrete to give my legs just a slight balance challenge. I measure in time not steps. After 45 mins (with a short rest in between fir stretching) I then stop, have a mug of tea and ice up for 30 mins…
This routine over the past two weeks has helped. Yesterday I went back to the physio who was very pleased but she added three exercises which, at the time, I thought “easy Peasy”… nope!
Really sore this morning and waiting for my dose of parecetemol and eyeing up the remaining bottle of morphine..
Today is the start of the 6th week so I really empathise with you.
We will get there and it will take as long as our own bodies dictate! Best of luck!
