Been having a stomach ache for 3 days so far today it is feeling worse on a scale of 1 to 10 my pain in my stomach is 10 what do i have and what's the cure ?

Such pain means...: It means a visit to one's doctor or E.R. Abdominal pain can be from many things. Stomach acid problems cause pain, as do ulcers, pancreatitis, or gallstones. Appendicitis is always a concern (pain usually right lower abdomen, worsens over time, with fever coming on). If constipated for a while, stool backs up and causes pain. Gastrointestinal infections can cause pain, nausea, vomiting, and fever.
