I haven't pooped in 5 days?

Asked by savvy17 (52) December 23rd, 2016 from iPhone

Hello all- this is my first ever question on any kind of forum. But I need advice so why not? On Sunday (today is Friday) I was actually in the hospital because I had vomited 5 times and couldn’t keep any type of liquid down (not water, not Gatorade, not seltzer water), had a fever of 102.9, was dizzy, my muscles ached, and I had diarrhea. So they gave me Zofran for my nausea and Tylenol for my fever and after that everything was all fine and good. But since then I have not been able to poop and my stomach feels like I have to! I dont know if this is an after effect of the Stomach Flu or what but I am not a huge fan of this. Help me out please!!
