text: bumps on fingers... read more...? i have tiny bumps, not really the size of a grain of salt, but a little bigger, like you can feel it's there, at the joints of my fingers. i'm not sure what it is, but i'm positive it's not warts. these bumps are only on my right hand "ring finger" there are a few clustered ones at the top about 2 cm from the finger nail, and on the other side of my finger there is one bump at the second joint and another at the third. i don't think it's artheritis, cause i'm only 15, but i don't know if it strikes that young. thanks. what ever it is i think you should go to the doctor and stop trying to figure it out yourself, because it could be something serious and maybe it nothing just go to the doctor let your parents know what is going on so they can take you to the doctor.
