Hello.
Thank you for your query at DoctorSpring.com.
I understand your concern.
Good to know that your Crohn's is in remission.
You seem to be having on and off mild gastritis (inflammation of the stomach). This is causing the discomfort and the feeling of gas. And it will not be tender to touch.
Gastritis usually occurs due to excessive stress, a spicy diet etc., as a result of increased gastric acid production.
If you are facing excessive stress, then you need to take steps to de-stress yourself like meditation, yoga or whatever works for you.
In addition, please avoid spicy food.
You should take an OTC like Prilosec (Omeprazole 20 mg) , once in the night just before going to bed, for two weeks. This will take care of your symptoms.
I hope this was helpful.
Feel free to ask queries.
Regards.
