Red, itchy, rash/ bite/scab/irritaited skin/ something, unbearably painful, Need help, please!!

I have very similar symptoms I'm going to post my own questions soon, but I want to double check with your guys first, and look for similar effects. The docter here dismissed me and found nothing, I am worried it may be some kind of new disease / sickness, everyone who I have talked to with similar symptoms have been dismissed by docters reporting back nothing new. I have been feeling itchy for awhile, but this morning at 3AM I feel this unbearablle pain shooting through my body, I also have these weird hive like itchy bumps everywhere. I think it started on my arms, its now on my should stomach, lower chest, and 1 near my penis. . . All very itchy, and cause unbearable pain, I litterally was moving and kicking around constantly like a petrifiying / searing pain, I don't want to take anything as I have had bad experiance with drugs. . . I am going to tak a picture of my rash thing I want to confirm that we have the same thing, then I want to know anything you have done recently, new or out of the ordinary prior to getting this itch. I have a few things. . . but mostly I sit in my house and do nothing everyday. . . Not much change. . There was 1 morning I couldnt sleep so I went on a walk at 2:00 AM, came back at 5:00AM, I didnt want to bother my family sleeping so I left... was dozing off by a tree, bird woke me up, and I went back home. . . the next day I got sleeping pills with a pain sideeffect, or the otherway around rather. . . Diphydramine 50mg, and acetamophen 500mg
I took 3 of them to knock me out for several nights in a row. Also the only other thing out of the ordinary is I got a package in the mail from my mother from japan / singapour/peru, full of suveniers and candy from forgien cultures. . ., everything else is normal. .

It looks like small bug bites or hives, itches insanly, pain shoots through body I have had it for awhile, family doctor doesnt know what it is, got it recently, rest of family isn't getting it, I have washed all my clothes, and bedsheets, cleaned up about everything, and shower 3 times a day but it seems to worsen. . rather then get better. . As soon as it stopped itching so unbearably that I was floppying around looked probably like I was having a spasem, I got on the enternet and started looking for something, I'm posting everywhere to find an anwser, and hopefully a cure. . its still itchy now but I am managing.

Also I am 18 Male. . .
