I realized a few years ago that I get gassy anytime I am around people. This has developed into a strong anxiety. When I'm on my own I can go a whole day and passs gas a few times but once I find myself in the midst of people it gets worse. It's so embarrassing I have tried everything. I stoppped taking diary products I even went days without food and it still occurs. Due to my trousers mostly has a foul smell at the end of the day. Any suggestions as to what might be the cause?
