I am having pain in my right side of my back. I had a total hip replacement in January of this year....so I haven t been physically mobile for almost 2 yrs prior. I am wondering since the surgery and just recently I have been doing more mopping, vacuuming & carpet cleaning if my pain is from over exertion of muscles in my right lower back/side are from this. I am right handed. Also, I have aquired a puppy who is almost 8 months old & weighs about 50 lbs.
