Hi, my sister has been having this vomiting sensation and severe headache for years now. She is 41yrs now. Currently the symptoms are frequent. Symptons include constant vomiting white stuff only and sometimes yellow stuff. the vomiting sensation can last for days. The vomiting is compounded by severe headache and fatigue. No stomach ache or diarrhorea. When she drink coldwater, she can feel the cold sensation through her throat to chest area. The doctord give her vomiting tablets to stop vomiting and antibiotics and panadol for headache. No TB. NO MALARIA. They said Thyphoid. But still nothing to pin point the frequent vomiting and headache. Appreciate your help.
