Question: I've been told I need a hip replacement. Can a bad hip cause pain all the way down the leg to the shin?

The reason I'm asking is that I also have back issues - stenosis, herniated discs, overlapping discs. I started having leg problems 10 years ago when overnight my right leg practically went to jelly and I experienced the same ferocious pain in the quad, knee and down into the shin that I'm experiencing now in the left leg. There was some permanent muscle wasting in the right leg. It was a slow, years-long recovery, but that leg has since regained some of its strength and I rarely have any pain in it.
What I'm saying is this seems like XXXXXXX vu. The only difference is that the left leg still supports my weight. Over the years since the right leg "blew up" on me, I've become increasingly clumsy and had multiple falls. Now it feels like I'm losing much of my lower body strength, one side at a time.
I am a widow with a farm and lots of heavy lifting to do each day. As a result of that and the slow, steady lessening of lower body strength, my upper body strength is great - probably superior to that of many women my age. I would like to be able to continue this lifestyle. But this steady erosion or body strength is a concern, one that I doubt a hip replacement will remedy.
Thank you for any advice you can give! XXXXXXX

Thank you.
