Suffering From Bouts And Badass Itching All Over The Body. Cure?

I am currently suffering from bouts of badass itching all over my upper torso with barely any signs of hives, redness or swelling.

At 48 years of age I am troubled by extreme bouts of evening itches to which only 5ths of Even Williams can slightly cure. I have been to 4 different MD's ranging in years of service from 20 years to 40 years, neurologists, allergists, dermatologists, physical therapists, chiropractors and even a voodoo Dr. on-line for just the shits-and-grins of it. No one can figure out what I have. I have been tested with everything known to man, woman and freaks alike. Don’t try and tell me something cliché that you KNOW I have already researched after 4+ years of living in hell. I need something know one has ever heard before that has at least an IQ above 10 wouldn’t have already researched in desperation.

So here’s the run down, I can go all day without an episode and even sometimes close to a week without episodes but never do I go a full week without a full-on itch-fest for at least 2 hours at a time and only then after I down a 5th of bourbon will I come out unscathed. On the normal it is every other day I do this.

I have had my fill of this and the thousands of dollars to every dick that cannot tell me what I have or how to fix it.

Before I call this life quits can anyone give me a ray of hope that it is something someone else has already gone through and they now how to fix it? Anyone?
