I had the same concern. I know it's a bit vain but it's one of those things that I knew would make me self-conscious and if I could find a way to shave, it's a bit of "normalcy" in my world.
So, before surgery, I got my legs waxed. (First time ever for me and it stung a bit but it was quickly over.) It lasted about 3 weeks but there were a few spots that she missed that were bothering me. About 2 weeks after surgery, I decided to try to do something about it. I have a big soaking tub (that I never use) and so I put my shower chair in it. I put a chair in my bathroom before surgery so I could sit down to get dressed, put on my sox, etc. I slid from that chair to the ledge at the tub to the shower chair. I then took a razor and “stuck it” into the end of my clothing stick thingy. To get my leg lathered up, I used my loofah on a stick. It’s certainly not the best shaving job I’ve ever done but it’s better than it was. I also had a pitcher of water already filled and was able to strategically pour it over my leg to rinse it off. This worked pretty well and I'm going to do it again this weekend. Although I have broken the 90* rule on a few occasions, I'm trying to abide by it so this is my compromise. The trick is finding a razor that will fit into the stick thing without moving. It took 3 different kinds for this!
