Hi
This is my case pretty weird I am sure
Before I start I need to tell you I have had blood test STD , HIV and CBC all negative and perfet health , I don't smoke and don't drink, so my blood is kind of pure
But, I caught , what I would call a penis bacterial infection (the doctor told me it is not herpes or any related std, as, all my test were neg), I got a pimple kind of no itching, I scratched it and it became like a huge circle swollen like a burn, then open into a blister and finally healed after 4 weeks!! And now it has been 5 weeks and you can see some stain , like a jelly fish , man o war bite , u know when you have some stretch skin lines , somehting like that , basically it has healed but I wonder if I will have this for ever :), it is located on the right side of the penis shaft, that is it nothing else elsewhere...
And how bizarre it is my left upper lymph node that was a little swollen
The doctor prescribed me Levaquin 500mg for 6 days... to be honest I don't know if it killed the virus or bacteria, because I still have a little tiny limph node swollen , really tiny , compare to what I had before...
I need to precise , never had any itching, no blood, no pain when I urinate never, no pain if I was masturbating etc...
To me it looked like maybe a spider or some sea insect bite... what do you think??
I have attached 1 pic of the line spot stain I have left :) so maybe it will help to diagnose.I really wonder if I have to let it go like any bacterial infection or go again to the doctor and get another prescription?

I'm surprised your doc didn't actually take a sample to better diagnose which infection it was... which tells me that he wasn't too worried about it. If you've taken your full course of antibiotics, chances are, unless it's some super-strain, the infection "should" be taken care of.

As far as the "stretch marks," it looks more like scarring from the blister than an actual infection.
