Thanks for writing your query.
I would suggest that you should get following investigations done :-
1. Liver Function Test (LFT)
2. Complete Blood Count
4. Kidney Function Test.
You should take antacid like Omeprazole
20 mg once a day along with Domperidone
Pain killer like Mefenemic acid along with antispasmodic like Dicycloverine
, will help in reducing pain in abdomen and pain in legs.
Also take care of your diet and follow some precautions like :-
1. Avoid spicy and oily foods.
2. Avoid cigarette/alcohol.
3. Donot miss a meal.
If the problem persists, get yourself examined clinically and take any medicine under medical supervision only.
I hope this is helpful to you.
