You must have confused a hallux valgus
with a bunion
. If your great toe grows outwards causing a hump at the 1st meta tarso-phalengeal joint then its hallux valgus. if accompanied by a chronic soft tissue
swelling over the hump then its bunion. Nevertheless, if the x rays r normal it means it aint either of'em. So this is very likely a malformation/benign tumour. I suggest go right ahead and take it out under local anaesthesia and dont forget to send the removed tissue for histopathology.
Good luck and remember..always follow evidence based medicine
