I doubt it, but it's possible that you had a primary herpetic outbreak. In other words, if you contract
herpes, the first oral outbreak is more severe than subsequent ones. It is usually accompanied by a
fever. HPV, or the human papiloma virus is also common in the oral cavity and would appear as warts.
It is hard to tell without an examination, but the bumps on your tongue may just be enlarged
taste buds. You should have a large V-shaped row along the back of your tongue and bristle shaped ones towards the front.
The most common cause of blood in the mouth is
gingivitis, or an inflammation of the gums. Brushing and flossing can both cause the gums to bleed if gingivitis is present. Keep in mind, that a small drop of blood, in the mouth, will seem like more because it mixes with saliva. The 'cure' for gingivitis is the removal of
plaque through brushing, flossing, and a professional cleaning.
It is always a good idea to be tested for STD's to set your mind at ease and/or have a dental examination.
