I feel nausea  getting up car and bus due to bad smell inside car and bus. I can't tolerate any strong smell also , get headache . I feel severe nausea vertigo headache as soon as bus and car start running and after going small distance vomiting . And nausea headache continue for 12 hours to next day . This problem is since childhood and now I am 28 years old male. And for that reason I can't go out and I can't study . I consulted many good allopathy and homeopathy doctor allergic specialist. But they all told as you can't tolerate the smell inside bus and car so you have nothing other than avoid it. So, I have nothing to do .
