<s>[INST] Hi. I just suddenly got this pain in my stomach last night. I woke up about 3 a.m and threw up. The pain is from my ribs down to the rest of my stomach. I'm currently on my period too. This pain is a stabbing overwelming pain. Do you have any idea what it could be? [/INST] Hi,It seems that this might be abdominal colic due to period or stomach upset.Many a time colic produces vomiting as well.Take Meftal spas or Cyclopam to get relief.Take light diet.Ok and take care. </s>
