I am new here and saw this post. I got this horrible "virus" or whatever you want to call it about 6 years ago. For me it lasted
about 2 months and the itch and pain was soo bad I had my dh and kids use my dogs brush with the metal bristles to scratch me and they could never scratch hard enough. The only medicine that helped was (racking brain, oh the fog),,,,,finally after 15 mins of searching LOL (nurse for 15 years, hehe) Atarax aka Hydroxyzine! I took 2 50mg tabs a few times a day, benadryl didnt cut it!
Hope this helps,
