My husband actually would shave mine for the first month. Then after I was able to stretch a little I can now manage my own in the shower. I have to bend the leg I am not shaving while standing on it to reach the other. I have a feeling I may be doing some bending maybe but I do my best to keep my back straight. Another way is in the tub when taking a bath. I looked into an electric shaver too to use in bed. That is the way I did it. If you don't have a man around to help or that is willing, maybe a friend could help ya? If you are in the shower, you could wear a bathing suit. Wish you well,I understand!!!!
I don't know what kind of surgery you are having or had, but after my microdiscectomy I just had to shave. This is how I did it one week post op:
I filled the tub about 1/2 way with warm water. I sat on the edge of the tub with my legs in the water and I leaned forward to lather my legs up with shaving cream and to shave, being very careful not to bend. This technique might not work if you have a fusion.
I have a bench built in to my shower that I can sit on if I need to. I put a towel down first so I don't slip off, and then bring my foot up to my other knee (like I do when I'm putting my shoes on). From there I can do a half-decent job. Now that I'm steadier and feeling better, I can also lift my leg up to the bench while I'm standing, and that works a little better than the seated method (that way I tended to miss spots).
