Suggest Remedy For Sharp Pain In Left Side From Under Ribcage To Belly Button And Back

i just started about 2 hrs ago having a sharp pain in my left side that stretches from under my ribcage to my belly button and tight pain in my back on the left side. when i bend over to touch my toes the pain hurts worse around my belly button section. i feel bloated on my left side. it does not hurt worse when i push on that area and my left side of my back feels better when i rub the musle for a little bit. no fever, no vomiting but soft stools since yesterday. have been under lot of stress past two days. its tolerable but not getting worse or better. im not a drinker. i need to know if its something to worry about now or can wait till monday if it still persists.? i am a 33 yr old female.
