Hi,
It seems you are most likely suffering from colitis but as the pain has been present for quite some time now and considering your family history, I would recommend that you consult a physician for a thorough physical.
Colitis is inflammation of the inner lining of the colon. It may cause abdominal pain and diarrhea with or without blood. Fever may be present. It may be accompanied by nausea. As you presently do not have diarrhea, it seems like it is a subclinical infection). While many causes of colon inflammation may be self-limiting and can be treated with diet and observation, it is important to determine why inflammation has occurred, because of the potential for a more serious diagnosis. I would recommend the following-
1) Get an immediate consult with gastroenterologist and gynecologist for a through physical. The gastroenterologist might consider you for a colonoscopy and stool blood test. The gynecologist might give you a pelvic examination and a transvaginal ultrasonography.
2) Start antibiotic for eradication of the organism .Begin with Tab. Ciprofloxacin 500 mg and Tab. Ornidazole 500mg. Stay away from drinking alcohol as it may cause side effects with ornidazole. Ciprofloxacin is sometimes associated with photosensitivity, so it's advisable to use sun screen if you go out.
3) Drink plenty of fluids as you might get dehydrated and it complicates the infection. Mix a sachet of electro powder to a 150 ml of water and drink it in the mornings.
4) Eat a good balanced diet with good portion of proteins carbohydrates and vitamins. Consume diet rich in green leafy vegetables and milk.
Thank you.
