Hello, a week and a half ago my fiance got

Patient: Hello, a week and a half ago my fiance got very sick. He was vomiting, headache, blood in his stool, dizzy spells that made him fall over, nausea. He went to the doctor and they thought it was a virus so they gave home a shot. The shot didn’t work and so we went back in. They said it is bppv. He’s been put on medication for the nausea and dizziness. He has been having the dizzy spells for over a week now. He went into work today and became really sick. Nausea dizziness hot and cold flashes headach confusion shaking. Now we have another appointment with our doctor later to see him. He also hit his head pretty hard about a week to 2 weeks ago.. would that have an effect? Do you have an idea of what it could be?

Doctor:
