Starting out with leg pain

Last night the pain I’ve been experiencing in my right lower back moved to the hip portion of my right leg.  I’ve looked it up on the web and I may have over-extended the muscles in my back.  That would not be a far stretch considering I rebuilt and reinstalled a big patio slider door a few days ago.  I had been noticing pain in my back a few days ago but had to drive for 700 miles to VA for my new project.   I can walk ok and when I sit in just the right position the pain is bearable.
We are planning to drive another 3 hours to Adventure Bound Camping Resorts - Washington DC, 5381 Sands Rd, Lothian, MD 20711
Hopefully there is a train nearby that I can ride into Falls Church VA to work everyday so Karen does not end up stranded.
We will setup camp this afternoon and may extend the slideouts.
The aquahot cut off twice last night and I had to click the switch up/down in order to restart it.
The weather is in the 30’s here so the AH is necessary.  I also need to change out the heater elements in the AH so we can use electric for water and some heat.
