Sliding hernia in a 12 year old. Help

Has anyone got any advice? My son has been diagnosed with a sliding hernia after suffering 4 days of sickness every 6 weeks since September. It really knocks him off his feet. He's missing so much schooling, what can I do?

Oh bless you !! I feel for your son 😢 it really is awful it is new to me and I am suffering, let alone a child ! Some one will give you some good advice X good luck xx

What are his symptoms?  And is there anything that seems to trigger his symptoms?

Starts usually with a nose bleed and then cant keep anything down for about 3 days. Tried to look for triggers and food triggers and nothing is screaming out at us
