my stomach hurts, right below my rib cage. it's been hurting on and off for 5 days now. it's not a gasy, bloaty pain, but it is a sharp pain. and it feels like someone is squeezing my stomach really really hard. the pain comes and goes, but when it does hurt, it hurts REALLY BAD...and i don't have a fever, nor have i thrown up, so I don't know what's wrong.
