The cast on my arm is a fuckin bitch..
 

It itches like hell..
It smells god damn awful.. like onions but worse..
The sweat in congealing and adding to the problem..
It's costing me money..
I keep knocking my girlfriends head with it and she keeps moaning that it's hard..

What do I do? remove it myself or put up with it another week until I go to the hospital to have it removed?

Get a long thin stick and use it to scratch the itching parts.
