Hello Dr,
I dont really know what makes me having armpit odor (really strong but I and my family just can smell it a little) but other people have sniffed(itchy and headache) when they\’re close to me (about 10m). Before i used deodorant (old spice), i didnt have the armpit odor, it just happened when i used the deodorant over night ~3 times. After that, i cant do anything to make the odor dissappeared. Can you give me some solutions?
sorry about my English.
Thank you,
