Is it true that dermatologists are unable to diagnose a PS and
cannot be trusted in their judgement? I read this on the internet and this worries me quite a lot. Because the problem
is that I have 2 spots in the crack which one time became thick
like a pimple and then vanished a few days later. One of the spots
itched and it kind of reacted to being touched or scratched. Every
time when I seeked it and touched it or slightly scratched it
because it also itched a bit it seemed to "react" and it become
more elevated comparable to a bee-sting which itches and when you
scratch it it becomes more elevated. Is this typical for a PS?
And the other bump which I had also became thick like the first one
and looked like a pimple and also bled a bit and then I went to the
dermatologist and the first one said it's a PS. Then I went to a
professor of dermatology 2 days later on showed it to him and he
said it's not a PS. And then I went to a third dermatologist and he
also said it's not a PS but he offered me to cut it out if it
bothers me.
But if it's not a PS then what is it? Both spots are still
elevated, I can still feel that something is there when I stretch
the skin and run the finger over it. This really worries me. If
this isn't a PS then what is it? Or what if these 2 things are PS
and from the outside you simply don't see them? Now I'm concerned
again especially now where I read that dermatologists aren't to be
trusted.
