I guess what I’m asking is if a doctor has examined the entire body, vitals, blood pressure, temp, blood sugar, liver function, heart function, kidney function, etc. to see if there’s some illness, infection, etc, Or did you see an orthopedic doctor who just looks at your painful knee and says it’s a knee problem? Most ortho doctors look at the limb in question and not explore the whole body to see what the core problem is.
