7 months out... Itchy skin?

I was wondering if anyone has experienced itchy skin. Its not exactly a heat rash but it is kind of like that. It comes and goes... mostly behind my knees, elbows and under arms. Also around my strech marks. I lotion, I have tried to change my laundry soaps, etc to hypo allergenic. Nothing seems to help. I am hydrated and eating well balanced meals. I take my vitamins and suppliments. I am puzzled. I made an appt with a dermatolgist but I cant get in for another month. Its very annoying. Any Info would be greatly appreciated. Thanks...

Might be sweat or loose and/or rubbing skin related. I sometimes get itchy behind my knees real bad too.

 OMG, I know exactly what you mean.  I shower 2x a day, lotion, powder, etc.  my stretch marks itch all the time.  It's only started recently.  There is no redness or swelling, i am sure its not cadidiasis.  If you find something that works let me know.  I have a PCP appointment in August and was going to ask him if it's still an issue.  It hasn't been more than an annoyance for now.

I had that behind my knees! It went away around 4 1/2 months out.
