Flagyl Abdominal Pain Causes and Reviews


Your abdomen extends from below your chest to your groin. Some people call it the stomach, but your abdomen contains many other important organs. Pain in the abdomen can come from any one of them. The pain may start somewhere else, such as your chest. Severe pain doesn't always mean a serious problem. Nor does mild pain mean a problem is not serious.

Call your health care provider if mild pain lasts a week or more or if you have pain with other symptoms. Get medical help immediately if

  • You have abdominal pain that is sudden and sharp
  • You also have pain in your chest, neck or shoulder
  • You're vomiting blood or have blood in your stool
  • Your abdomen is stiff, hard and tender to touch
  • You can't move your bowels, especially if you're also vomiting

Flagyl Abdominal Pain Reviews

Thu, 07 Jan 2010
The exact same thing happened to me after I was prescribed high dose Flagyl for 5 days for suspected diverticulitis (painful bloating, frothy yellow diarrhea, excessive foul gas, etc.) my doc also put me on a Clear Liquid Diet for 3 days before I had this episode... I called 911 from work because I felt chest tightness, shortness of breath, extremely lightheaded, and couldn't stand up or walk without almost passing out. I was confused also with difficulty concentrating and speaking. EMTs found my blood pressure to be 170/100 and my EKG showed a "Right Bundle Branch Block". I felt better after they gave me nitroglycerin and 4 baby aspirins. At the ER my EKGs and cardiac enzymes were normal. A CT scan of my abdomen failed to show any diverticulitis- they told me it looked completely normal. They also said I was dehydrated with a slightly low potassium level which was to be expected after 9 days of diarrhea. They thought my episode was caused by severe intestinal spasms probably due to side effects of the Flagyl and ibuprofen I had taken that morning on basically an empty stomach!

I am currenty on Flagyl for a pelvic infection in combination with vibramyacin. This morning I took the vibramyacin and then was planning on taking the Flagyl an hour later, but I spent the this morning vomiting. I called the dr. and was told by my dr. to continue taking both but with food..vibramyacin said to take on empty stomach, but I think the Flagyl was effecting me from the night before and not drinking enough water in combo with the vibramyacin .. and I think that's why I threw up I did not take the Flagyl before I threw up, however, after I was ok and spoke to the dr hours later , he told me to continue taking both but I took the Flagyl thinking it was the vibramyacin causing all the trouble, I had stomach burning all day and then just a half hour ago I took the Flagyl again and immedialtey had I realized soon after taking it again that it is the culprit causing a heartburn like burning senstation in my stomach and lower esophogas... I am calling my dr. tomorrow again to tell him that I can't deal with this. I tried to push through since I want to be fully rid of the pelvic infection but this is ridiculous. It feels like a horrible heartburn burning sensation.
