dime size itchy rash

[Contacto]

Three months ago I got two red rashes, one right above the knee in one leg and the other right behind it in the other. They were both the size of a dime and circular with something that looked like a bite mark in the middle. They were also bright red and both lasted for about two weeks with an intense itch. When they subsided they left what appeared like a dark bruise witch it is still faintly visible. After the first episode I got a second one (3 weeks after) on the back of my leg with the difference that the second one I believe got infected and started to hurt a lot. A little scab formed and when I showered it fell and I could see a little hole on my skin. I still have the scar and the same bruise like mark as with the others. Today I woke up with another of this rashes just below my neck and it itches a lot but Im not scratching. What can I do?

I think you can and should make an appointment and see a doctor.  As near as I can tell, these sound like bites of some sort rather than a rash.  The marks that are left over will fade and go away if you leave them alone.  The fact that your wife doesn't have these does not rule out bites, since people differ in their sensitivities.  But the only way you're going to know for sure is to be seen in person.

Best.

I forgot to mention that I recently changed address (different city) including bed, I do not have any pets and my wife does not present any of this symptoms.
