Pain is subjective and doctors realize that...and the non-asshole doctors will give you what you want/need.
Here's a few things to try.
Enter the office, complain of horrible pain. Make sure you describe it as a muscle pain and not a 'broken bone' pain, or he'll want to charge you three billion dollars for an x-ray you don't need.
Scenario One: He gives you Ultram or some worthless shit. Take it and thank him. Two/three hours later call him up. Tell him you've already had to take TWICE the amount he reccomended and it's not even touching the pain. If you are a clean-cut looking kid it should work. For best results have one of your parents (See: You pretending to be your parents, or a friend, or hell, use your parents, etc) call in for you, as you are in 'too much pain'. Doctors are more inclined to trust the parent than the teenage child.
When he sees the Tramadol isn't working, he'll more than likely go to Hydrocodone.
Scenario 2: Now this is a stretch, but it worked for me PERFECTLY.
Go to the hospital. Yup, the hospital. Complain about the pain the wreck has caused..the unbearable pain. The doctor SHOULD give you a prescription...but this will only be enough to get you by until you see your REAL doctor.
Enter Real Doctor: Tell him the doc at the hospital gave you some "Hydrocodeine" <Doctors LOVE it when you pronounce it that way...it shows you don't know anything about abusing evil drugs> and it worked great, but you only have 2 left. He should give you a brand new prescription.
Now...this is the part that I was referring to when I said it was a stretch. As I said, I don't know how severe your damage/pain really is, so I can't say it will work for you, but it did for me.
I was in a car wreck. Went to the hospital, got my Hydrocodone RX. Filled it, abused accordingly. Then went to my physician. Got another prescription for Hydrocodone.
Then, when I went BACK to the surgeon <Had to have surgery>, I told him that I was taking some "Hydrocodeine stuff" and that it worked, but my PHARMACIST was concerned because I was taking so much APAP with it...here's what hooked it...I had to pull out a peice of paper from my pocket to remember "APAP". This showed the surgeon that I had no idea what drugs were...He said, and I quote:
"Yah, pharmacists are always concerned about Acetaminephen...but it's no big deal really...but if you want I can give you something with less APAP in it".
ME: "I really would like that, because I hear it's bad for your liver and I have a history of Liver problems in my family"
I walked out of the hospital with a prescription for Norco.
So from ONE measly wreck, I got 3 prescriptions.
If you play your cards right, you can always beat the system.
