If you had appendicitis you'd be begging for a hospital even if you do have a high pain tolerance. I suggest you opt for one day of bed rest and apply a heating pad to the area to relieve pain. If that doesn't go away get into a doctor and see what they can do for you.
UPDATE: The pain has now moved up to the middle of my stomach above the belly button, there's a pressure feeling there and it's almost like there's vomit in the back of my throat. Heating Pad provides comfort but not a lot.
You may have a GI track issue. Try a liquid diet for a whole day and take 2 dulce lax 5mg tablets during that day. I have chrons which causes an incredible amount of abdominal pain and that tends to help. It may be really gross but you should feel tons better if it is a possible GI track issue. I know your hurting but it also helps if you can get up and walk around, walking helps pain, especially abdominal pain.
thank you so much! The pain really just moves around all day, I'll try to do the liquid diet tomorrow :)
