Thanks for your query.
I will try my best to provide you with best possible professional recommendations to your questions.
I think you are suffering from stress
. Pentoprazole is not responsible for the side effects you have mentioned.
I advice you to take pentoprazole for week and avoid consumption of spicy food, alcohol and smoking
. I think the tests are not required. You are stressed, i advice not to panic, it is simple gastritis which will be relieved.
Yet again, I do hope that you have found something helpful and I will be glad to answer any further queries.
