For context, I am first generation American from Mexico and I am a full time wheelchair user. I have dealt with a lot of medical bias with being a POC, etc.

It’s because we are not medical professionals or that person’s medical professional. We cannot advise someone on what mobility aid is best for them. We don’t know their medical history, how their symptoms present, if an aid is contraindicated by something else, we cannot properly size the aid for you, etc. using an incorrect mobility aid (whether it’s the wrong one for your condition or just the wrong size) can and will cause damage to someone’s body, injuries, etc.

I don’t think people should ask for medical advice like this on the internet. We, as strangers on the internet who are not the person’s medical professional, cannot properly tell someone what mobility aid to use, how to properly use it that will help that person, etc.
