Extreme Itch on Legs (Had Strep on Skin)

[candig4265]

I was fighting an extremely itchy rash that originally started on my ring finger, then ended up spreading over the course of a year to my lower legs, arm pits, neck and small circular spots on different areas of my body.  The itch was so bad, I was trying everything to stop it.  It would keep me awake at night, scratching until my legs were bleeding in areas.  It was such a deep itch that just kept getting worse the more you itch.  After numerous skin biopsies and scary discussion of rare lymphomas, my dermatologist ordered the blood strep test.  The test came back positive and they realized I had it for well over 1 1/2 years (I never had strep throat).  I was treated with months of oral medication and skin creams.  The rash  has completely cleared up and I've been feeling itch-free since September.  Since then, I have discoloration on my legs.  The doctors say it's light scarring from the rash I had.  Recently though, whenver I shave my legs, I get extremely itchy again.  I've always moisturized, but my skin doesn't seem to be soaking up the moisture.  And, the severe itch is back again.  I read about someone who described an itch as "pins and needles" which is what this feels like when it's not itched.  It's a tickling pins and needles that I'm constantly having on my legs whether I shave or not.  Having an itch after shaving has never been a problem for me.  But two weeks ago, I'm getting redness under my arms (armpit area) again.  However, I'm not getting the under-skin blister like bumps as with the strep rash.  Has anyone had or are going through something like this?  Any suggestions for something that will cure the extreme itch?  I have allergies and food sensitivities so I've again been watching my diet and what I eat.
