Thanks a lot to Choon Hui, i found out more bout this thingy call Bunions. Its usually develop by wearing shoes that are tight or too small for your feet causing your metatarsophalangeal joint (the place where bunions grow) to stick out.
I guess all those high heels that i wore back home finally gives me a warning sign now.
