It could be a parasite I suppose, hard to know. We think it came from an undercooked burger and is food poisoning of some sort, as my own stomach problems started a few hours after eating in a burger restaurant (that looked, at least, to be clean and reputable but you just never know!). We were on bottled water only when we were there (including for teeth cleaning), lots of hand washing/sanitiser etc. I think my stomach is a little delicate as a result of having a ‘nervous stomach’, but my husband generally has a strong constitution. Despite also suffering from anxiety, his stomach/bowels are never affected by his moods in the way mine are!
We were still able to enjoy the holiday, we were just a little hampered by dodgy bellies! It’s not the worst I’ve ever felt or anything, it’s just been quite prolonged and doesn’t seem to be getting any better which is weird.
Thanks so much for replying!
