My scalp tends to stink worse when i have headaches.my friends do smell it.fingers smell when touched.can it be contracted from a dogs skin infection?

Ringworm from dog: I suspect you may have "ringworm", which is a fungal infection commonly contracted from pets. These fungi eat keratin, the material found in the outer layer of skin and hair. These fungi love it even more when it's a warm and moist environment - like now in the summertime. I don't think the headaches are related, but you may need some antifungal treatment - good to show your scalp to a doctor.
