My mother, age 66 years is suffering from severe gastric trouble. She has had her gall bladder removed in the year 2000 and since then takes a lot of precautions while eating. Since last week she is having a lot of gas troubles, constipation. She had severe pain last tuesday and has been taking pantodac, norflox since past 1 week with little relief. However yesterday (tuesday) at night, she again had severe stomach pain. She has been eating very little food since the past week and is also constipated. Please advise. Tia.
