Im thinking of getting a mobility cane, but i don't know if I should ☹️

okay, i have been thinking about getting one for a while now but I just need some options ig. It hurts my legs sm to walk or stand up, my legs get weak and I almost fall. I get dizzy also if I stand up for to long. But somedays my legs will be fine, still barely i get pain those days. Idk i was just wondering about it ig. Give opinions please :3, (also i need to rest a lot and need to sit down or lean against smt)
