Can't keep food down. no fever. pain in my belly button and right side of my stomach. gallbladder?

Possibly: Your symptoms may be related to your gallbladder, but not necessarily. Gastritis, duodenitis, stomach/duodenal ulcers may also cause those. Further studies/tests are needed.

Abdominal pain: Your symptoms appear to be related to gallbladder. However, need to make sure you do not have acute appendicitis. Need to have further evaluation with a local physician or urgent care.

Could be: Appendicitis, so see a doctor or go to emergency immediately.
