Sir I am a ocd patients but last one week I stop medication because completed the course. I didn't go to visit the doctor because of my busy schedule. Yesterday I feel severe headache and vomiting feel then I take ranitidin 150 yesterday but nothing changes occur. Today's morning same incident happened I take pantop dsr but not cured so I recently go to hospital the doctor check my bp is 120/70 and give a pan 40 injection & ondem injection but it already 2 hours left but still not change in my health. Is it occurs for stress or any other issue?? How to prevent from this
