hmmm, not sure if anyone would be able to answer this without seeing it.
Is it like a clear bubble? or does it have more of a whiteish head? Itchy. or not?
Some times I get these "warts" that come and go... Mainly on my hands... Just one or two at a time on my palm. Small and like a clear bubble...,They go away on their own.
could be chicken pox... some people only get one or two bumps, but they itch, crust, and are usually redish.
Could be a clogged hair folicle, sweat pore, or the beginning of "chicken skin"... (Rough feeling of bumps on the skin. Many many bumps. Skin feels thick. Usually on the arms though so I doubt its that)
I am sensetive to nickel... I get a sorta raised itcy rash (clear fluid filled bumps) right under the spot the nickel was...I have had to stop wearing my favorite belt (nickel in the buckle) an awesome pair of jeans (nickel in the button) and have to wear sensetive ear rings. Does she have a pair of pants that the decals line up with the bumps? But then again... are they itchy?
More than likely its nothing... Just one of those roveing "what is this" bumps... But if you are worried about it the best thing to do is ask someone who can see it, and knows a little about what goes on with the body. :-)
You will probibly get some "whats she eat" or "what skin products" questions. And I would say that if it were something she eats or gets rubbed all over her, it would be all over and not localized to 2 bumps in 2 different places...
Good luck!!
