Even if some time has passed, a CT scan of brain, chest X-ray and
ECG should be done. It is quite possible that the hiccups
you had were due to something you ate that caused gastric irritation. However a brain bleed needs to be ruled out. If the bleed was small and localized, you may not feel any other symptoms.
Hope this helps. Please let me know if there is any thing else and do keep me posted. Take care!
