I dont now but i am definitely researching.
Any number of things could be the cause. Check with your doctor especially if it persists.
Improper breathing throughout the reverse crunches can cause abdominal pain. Lower abdominal pain may also be caused by the exercise itself, which works the lower abdomen. Pain on the right side of the abdomen can also be a symptom of appendicitis, so you should see a doctor if it persists.
Pregnancy. Or hormonal imbalances? not sure...
When there are no open skin wounds in the lower abdomen.
Very, very painful. There is sometimes swelling of the lower abdomen. Some people feel very sick, and some physically throw up. A burst cyst is sometimes accompanied with discharge from the vagina. It can cause fever/flu like symptoms such as shivers and a temperature and headache
You should go to your doctor and have an examination.
