When I suddenly get angry or shout or laugh a lot or excited I start feeling sick nd my head goes numb and I feel m falling down. I feel drowsy and my sight blurs. I never fainted but my head seems totally to burst off and I'm unable to react or speak for like half an hour next. If I try to my words feel like ringing inside my head and I feel dull unable to breathe proper and feel like lying down someplace. Even I have felt a small mound type on the right side of my forehead which probes when I get angry or hyper tensed. I have sinusitis but not migraine. I have referred to many doctors who end up giving painkillers or migraine tablets
