Some Years Ago I Had Noticed A Few Bumps/growths On

Some years ago I had noticed a few bumps/growths on the top of my feet (sort of middle of the insteps). These were VERY small (1/16th of an inch in diameter), not that visible (my natural skin tone) I went to a dermatologist and he passed it off as simple kerotoid (sp) eruptions and down played their importance. He also seemed irritated that I would care to have them removed. Flash forward a few years (or more) and they have clearly spread over the top of my foot, the ankles and top of my toes. I also believe this same low profile wart/bump has migrated to my upper inner thighs. They do not itch are virtually my skin tone but there presence and the fact that they are clearly multiplying (clustering?) is alarming not to mention becoming unsitely. Recently, I had gone to a Laser clinic to have skin tags removed and the technician noticed the bumps. On a subsequent vist, Laser Gal offered that she had described my problem to a Doctor friend of hers while at a seminar. He seemd to know immediately what it was and that its root cause originated in my nose as a crusty like lesion in the nostril which in time disappears but migrates and manifests itself as these bumps or eruptions on feet, ankles and other places like the inner thigh. I do not have the name of what he called the malady in front of me as I write this but I do remember that he suggested a 2% Bactroban ointment applied in the nostrils 2x daily would do the trick and actually kill whatever is "feeding" these things and promoting their spread and they would disappear in time. He suggested a rather long period of continued use of the Bactroban (2 months??) but when I looked Bactroban up most indications are that it be taken for only a week or so. To his credit I do remember quite awhile ago (predating the arrival of these things) having an unusual scab like crusty presence in one of my nostrils that lasted for a while and then disappeared. How's this all sound to you and do you have any thoughts or suggestions??
