Probably influenza. Nonetheless, coming here doesn't replace a doctor's office. Get checked.
are you having or had unprotected sex? is there a chance you could be pregnant?
Hi
Welcome to the MedHelp forum!
This could either be pregnancy or gut infection. If you have missed your periods then take a pregnancy test and see. If this is negative or pregnancy is totally ruled out, then it could be gut infection. Take an OTC lactobacillus preparation and yoghurt with your meals. Drink plenty of fluids. Eat light, do not stay hungry but eat simple things like toast, porridge, cereals, crackers etc. Take ORS. Take over the counter antacid and antiemetic (this SOS for vomiting). Watch out for a day or two with this treatment. If this does not help, consult a doctor. Hope this helps. Take care!
