If that is what you need, do it. It is to assist you and assisting you need.
Btw, my husband said something to me, last time we went grocery shopping, he said that he has noticed, that lately, I always push the shopping kart, which he always used to do. Now that he pointed it out, it's true, because I can walk better, holding on to the kart.
Maybe that means, that I will need something to hold me up, too.
Do what ever makes life easier for you.
