I have arthritis but it’s minor now with only flair ups occasionally when it’s cold. I walked in the morning shortly after waking up. I have been working and on my feet for a few days. My diet has varied a little in the past week. the pain is minor but sharp in the lower back area.

I’m just trying to cross-reference objectively, like House would, which possible factor is most likely the main cause of this particular pain. I also smoked a little green within the last week after not smoking for six months.
