I'm getting acidity and stomach pain since 3 days n continous motions but not lose motions. What to do?

See a doc. I take it that you are having continuous, but not loose bowel movements, acidity and stomach pain. Could be a bunch of things. See a doc.
Get checked out. If your symptoms continue, a md may be able to help. Consider trying some antacids or Prilosec in the meantime.
