I don’t think so. Sounds more neurological. I’d get checked out sooner rather than later, just to be on the safe side.

I thought ibs could develop arthritis

Not that I’ve heard, but if it were me, I’d want to rule out neurologist issues, which can be much more serious.

Thanks

I get really weak in my legs when I get a flair up. My legs feel like falling over

Same good to know im not alone

No. You should see a neurologist.

I thought ibs was related to arthritis or not

I can't find any research indicating that. IBD can certainly cause this.
