If you experience the pain below your ribs coming from the abdominal wall, you might be experiencing muscle pain (myalgia). Muscle pain is provoked when the affected muscle is active and calms when resting. Pressure on the muscle also causes pain.
If you feel the pain coming from inside the abdomen, then the pain might originate from the liver. In fact, the liver is not sensitive but its capsule is. Standard blood analyses (blood count, sedimentation, liver status…) and an abdominal ultrasound can be performed to exclude liver affection. You may consult your primary health provider for these diagnostics.
