Flagyl Muscle Spasms Causes and Reviews


Angina is chest pain or discomfort you feel when there is not enough blood flow to your heart muscle. Your heart muscle needs the oxygen that the blood carries. Angina may feel like pressure or a squeezing pain in your chest. It may feel like indigestion. You may also feel pain in your shoulders, arms, neck, jaw, or back.

Angina is a symptom of coronary artery disease (CAD), the most common heart disease. CAD happens when a sticky substance called plaque builds up in the arteries that supply blood to the heart, reducing blood flow.

There are three types of angina:

  • Stable angina is the most common type. It happens when the heart is working harder than usual. Stable angina has a regular pattern. Rest and medicines usually help.
  • Unstable angina is the most dangerous. It does not follow a pattern and can happen without physical exertion. It does not go away with rest or medicine. It is a sign that you could have a heart attack soon.
  • Variant angina is rare. It happens when you are resting. Medicines can help.

Not all chest pain or discomfort is angina. If you have chest pain, you should see your health care provider.

Flagyl Muscle Spasms 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.
