Hi,
Thanks for posting your query.
With the available described symptoms, there appears to be possibility of premenstrual tension or fecolith
impaction.
Palpable mass could be fecoliths which gets disappeared after passing stools.
You should consult with internal medicine specialist/ gastroenterologist and should go for thorough check up.
You should also go for
complete blood count, MRI scan abdomen,
thyroid profile, blood sugar, x ray abdomen and serum electrolytes.
Meanwhile, you should take
proton pump inhibitors along with prokinetics for relief of your symptoms.
You should also take plenty of water and perform increased physical activity.
Avoid oily and spicy food, tomatoes, citrus fruits, excessive tea & coffee, chocolates.
Take
soft diet along with yogurt.
Take care,
Dr. Mayank Bhargava
