@mykatz01 you may be having nerve or muscle issues regarding your leg? I’ve got osteoarthritis, osteoporosis, and chronic pain syndrome and sometimes when I’m tired or I have walked a distance slowly I develop a similar symptom. It has caused me to fall a few times over the years and thankfully I haven’t injured myself yet. Oddly these falls have been very intermittent, a year between falls as an example. I fell twice while on vacation pulling my wife down with me once. I used a cane for three months until my left shoulder and neck became painful. Have you had your back checked?
