Hey Jambo how are you?
It sounds like you're going through a stressful time and I wouldn't be surprised if that was having an effect on your health.
How are things now? I too have similar issues, I flit between diarrhea and constipation. Sometimes get a bit of pain. For trapped wind I use Deflatin, they work really well. Also hot water helps me (when I remember to make it!)
Hope you're ok
