I need a shoulder relacement but someone told me how painful it was. I'm chicken to consider doing it

I need both shoulders replaced both knees and left ankle. . These people want to turn me into robo cop or something 🤣🤣🤣

Me I pop in my back like snap Crackle and Pop 🤣🤣🤣 it really hurts not the ones in my back cuz it's kind of feels good when it cracks because it cracks a very slow and it's sounds like the popcorn kernels as they cooked. What really hurts is when your knees crack now that would make me scream sometimes I feel like the pengles all the way up my leg the cracking hurts and it I actually literally scream but and then there's times that it'll pop or crack and it doesn't hurt at all so I'm not sure what that's about but I'd rather it be cracking and I didn't feel it that's what hurts but I'm about to throw this everywhere so I have rheumatoid arthritis I've got a regular arthritis and I need two shoulder replacements and those suckers pop too I need an ankle replacement I need to knee replacement I'm going to be more of a robot than a human being pretty soon haha!!😁😁

What is crepitas
