Hi, it could be a case of Gastritis
so please use anti-ulcer drug like Omeprazole
If the pain does not subside it could be due to renal(Kidney
) stone right side or due to appendicitis
or sometimes due to gynecology problem. So please consult a surgeon if the pain does not subside or if you have sever pain. And remember to drink plenty of water. Regards, Dr.Ismail.
