Aio for using a walking stick with a mildly sprained knee (MCL)?

I stepped into a hip deep hole while hiking last week. It's not swelling just sore. I can gingerly walk up and down the stairs without a walking stick if I use the hand rails.

I can walk but I still have a slight limp on and off depending on what I am doing. I am slow to stand and sit and can't really lift heavy objects yet.

I tried a walking stick today and it was a lot more comfortable. But I feel like a wimp for depending on assistance for a sore knee. It's a very mild sprain
