Hello and welcome to HCM.
Thanks for putting your query here.
As you have got similar history in past,severe
abdominal pain radiating from front to back and nausea,it may be because of gastritis,
pancreatitis,
gall bladder stones or
renal stones.(you have not mentioned in which part of abdomen you get pain).
If i were your treating doctor,I recommend,
-Advice USG abdo.Further specific management depends on the results of USG.
-Cap
omeprazole or pantopD ,that includes combination with antiemetic,once in morning.
-If the pain is cramp like in lower part of abdomen,tab dicylcomine is recommended.
-Avoid hot ,spicy and high fat content food.
Avoid alcohol and non steroidal anti inflammatory drugs like ibuprofen or naproxen.
-Adequate intake of water.
-Avoid skipping breakfast.Have all meals at right time.
Hope this information helps.
Thanks and take care.
