Worst case scenario

Following from my previous post. I suspect i have either Nr-axspa or AS my clear trigger was food poisoning 7 months back.

I’m awaiting on my MRI test. I wanted to know what is the worst case scenario is. My biggest fear is being wheel chair bound. I never thought in a million years it would come to this.

Main pains that are on/off are spine, neck, heels, back, SI joints. I know theres something wrong.

Is this that bad that it can potentially kill us?
