Seem to be having an ache/pain in both sides of my body just above the hips. mainly below the rib cage at the back. experienced a slight loss of appetite over the last few days and noticed that food is taking longer to digest?

Backache: Have you been exercising or doing housework that could have strained your back muscles? Do you sleep on a good mattress? Since the discomfort is bilateral, a kidney cause is unlikely. Your GI symptoms are rather nonspecific. I recommend avoiding activities that would stress your back muscles, take acetomenophen or an anti-inflammatory medication like ibuprofen with food only. See MD as needed.
