 [ Symptoms ] i have yellowish bumps on the instep of my feet [ Disease ] i am sorry you are experiencing this unfortunately it is impossible to diagnose a skin ailment without a physical examination i suggest you make an appointment to see your primary care provider he or she can look at the bumps and tell you what they are and whether or not they need to be treated weird bumps on the feet are not unusual because the feet take a beating from walking and get exposed to all kinds of viruses and bacteria that may be lurking on floors in carpets and so on fortunately most of these bumps are not serious and do not cause much harm    other than looking funky your primary care provider can tell you what is going on and refer you to a foot doctor if necessary good luck
