DS6 has suffered four consecutive nights of random acute pain in his groin/very lower abdomen. Second night he was crying out in his sleep 8-11pm, woke around midnight and vomited every 30-40 mins through the night until 6 by which time he was throwing up horrible yellow liquid (bile?) as his tummy was so empty. He was properly writhing around in pain, unable to stay still, pacing around the room, reminded me of a woman in labour (obviously not as extreme or we'd have gone to A&E) First, third and fourth night, he's been moaning in his sleep, waking and crying, writhing in pain, needed paracetamol and a heat pack but managed to go back to sleep.
During day time periods he's been relatively fine- maybe a little tired/up and down, but mostly full of beans, so we keep thinking he's better/fine then it happens again in the evening.
Possibly relevant history:
We swim frequently and he will often complain his tummy hurts when swimming which made me think maybe a strained muscle (?)
He's had a couple of instances of tummy pain and vomiting recently, maybe 2 or 3 in a couple of months
He's not a drama king/moaner etc- vomited at school and didn't tell anyone, never really makes a fuss, is one to tough out injuries usually
Not sure if he's just got a bug that he needs to get over, or if we should be more concerned and getting him seen. Sort of leaning towards getting him seen but unsure if it will just resolve on its own 🤔
