Hi am worried about my partner he has been constantly sick a lot today, he has stomach cramps too he gets very hot and achy before being sick. He also has the pains still in stomach after beening sick. On Tuesday night passed he was sick once and had constant pains, the next morning he was absoulety fine he ate a kebab from local takeaway late at night. Would this be linked all together? Or do you think could be something else wrong.
