I know a lot about pain
1st -- his doc MUST give him somehting for the pain ya?
Ok here is what I can tell you....
He should take an anti-inflammatory, (like celebrex) and then try and see if you can get your hands (or have him ask his doc) on some neurontin -- this is a medication used for epilepsy AND becoming very popular for people who are in lots of pain, it is not very addictive, and it targets the nerves response mechanisms I believe, so it does help with pain.
I hate to say this, but there are other meds out there that would prolly make his life much more bearable --- meds such as oxycontin (you will hear a lot of bad things about this, but that is due to the abuse / addiction of the drug) or any form of oxycodone or hydromorphine. For some people this med has been a lifesaver...I am talking about people who are in so much pain they cannot get out of bed...yet after administering this drug, they are up and at 'em...no shit it is that strong. There is also a new med produced by Purdue Pharma (makers of Oxycontin) called palladone that is given to pateints that are in the worst pain possible (cancer, MS, burn victims) but it is growing in popularity especially in the UK..I guess the FDA asked Purdue to withdraw the drug after finding out the abuse potential was so great, more importantly it was also a very potent med that if mixed with alcohol could be quite lethal, due to overdose...this is because some people fake the hell out of thier pain, get the meds, then sell them on the blackmarket to junkies...who then do stupid ass shit w/ the meds and end up killing themselves etc etc...Anyway I hope this helps. If he is in absolutely horrific pain, a morhine pump works wonders as well. Sorry about your pop Justin.
