I am trying to figure out if my conditions could be related. My doctors keep telling me that they are separate issues, but i would like to know if these issues might be related:

I am an obese male weighing in at 252lbs (approx. 5'11''). I have had multiple surgery completed on my right foot, all unsuccessful at providing relief from a long time fracture. I have a limp, and swelling and pain after walking a few 100ft. or so.

Is it possible that this might have cause my Acute right lower back pain over time? I have had the limp for some +10 years now, and the back pain started up suddenly about 2 years ago.
