Hi my nephew was irritated with his body odor too. We tried different kinds of deodorant but it lasted onlyn for couple of hours. My friend reffered us to this site www.tawascrystal.com and it works. Lasted for more than 24 hrs. and all natural...Goodluck to your puberty...
This is something that does just happen all of the sudden when you are going through puberty. Make sure you shower every day and use your aniperperant (its the kind i use too) if you haven't gotten your period yet you might soon, along with underarm hair and pubic hair.
It sounds like you might still be going through the change of life..Oh you said you are sick. When you smell that is the bacteria on the skin. Make sure you wash well in the shower and use a antipersperiant deoderant..It also can smell from the foods that you eat I know If I eat onions or garlic I notice the next day there is an odor. Drink plenty of water to flush your system out.
