I just came back from a 2 week all inclusive holiday and 2 days after coming back I woke up in the middle of the night with really intense back pain which lead to me vomiting and also diarrhoea, I also then on/off was getting really bad stomach/back cramps (felt like being in labour lol) the vomiting lasted around 2am - 10am and then then diarrhoea calmed down most of the day as well. Since this (now 4 days later) whilst I'm generally fine and was since the day after I have been extremely tired (been basically napping everyday which is not like me), just don't feel myself and also still been experiencing the stomach/back cramps. The back cramps have pretty much subsided now but I have found my appetite to be a bit off and I have been feeling stomach cramps still and more bloating. I wouldn't say my bowel movements are completely normal either. Just wondered if anyone has experienced something similar? I'm more just a bit confused why I still have all these symptoms when I only had a short period of sickness. Not sure if it was food poisining or a stomach bug but I did see GP who did a urine dip test just to rule out a uti/kidney infection given the back pain. Just curious if anyone else found it took them a bit of time to get back to normal after something like this?
