Worth going to the doctors over?

Hey there, reader!

So about a week, a week and a half ago now, I noticed something about my penis.  I have no idea how this came about, but I had a small red patch on the left side of the tip of my penis, on my foreskin.  There were a few bumps on this patch, and while they didn't hurt when touched, it stung like buggery when I pulled my foreskin back.  This was quite a problem, the reasons as to why I won't go into detail about.

I wasn't sure what it was, but I figured I'd wait a day or two to see how it turned out.  And as it turned out, two or three days later, the bumps had simply...  Vanished.  The place they had been was no longer red, but it was somewhat dry and had very hard, flaky skin.  It stung when I picked at the flaky skin, so I elft it as was.  The next day, my penis looked like it always does, and the stinging was gone.  I figured it must have been a badly placed insect bite (I sleep naked).

Problem is, it's been another day or two, and the stinging's back, as is the flasky skin to a lesser extent.  It doesn't hurt when I actually pee, it's only when I pull my foreskin back that it hurts.  I shower just about every day, rarely going longer than three days without a shower, and I always wash beneath my foreskin.

I honestly have no idea what might have caused this.  The dotors in my town is always bucked up, you have to -magically- know when you're gonna havea  problem and book a month in advacne.  And seeing how quickly it came, went and came back has me wondering what the heck it could be.  There's also the fact that I'm 18 and in part time education, so if I get any perscription I'll have to pay through the nose.

So all in all, does anyone know what these bumps could have been, be it a random yeast infection I've heard so much about or jsut a bad insect bite?

Thanks in advance!
