I read and understand your concern. I am Chat Doctor answering your concern. As you are taking the antibiotics' treatment for the colonial sinus, it can cause gastritis. So as if you are not taking the treatment for the gastritis than you should take it. Pantoprazole with risperidone combination can help you to recover from acidity. Please avoid eating spicy foods. You can take small frequent meal but not single heavy meal. You can also take cold milk on every evening. This will neutralize the acid of the stomach. Pilonidal sinus can always require surgical correction as final treatment. So once your infection is cured you can take the surgery done. Hygiene maintenance by frequent cleaning and Chat Doctor. I will be happy to answer your further concern on bit.ly/ </s>
