What other symptoms do you have? Do you tend to sweat a lot? Poor digestion? Anything? Allergies?
I am not doubting you one bit, but perhaps, you can look for other symptoms and try to pinpoint what the cause (potential cause) of your odor issue.
Sometimes it can be difficult if you're not sure what "normal" is.
For example, I didn't know that deodorant needed to be dry since it was always wet for me, even now. I never ever knew you could even have dry deodorant. I thought as long as you put it on, it worked. lol
