Go on ebay & get a portable lumbar traction machine,they cost between $600 to $900 new & most peoples insurance pays for them,after peoples back pain stops they dump the units on ebay dirt cheap.
You can buy em all day long for $100, it would be the best money you ever spent twords back pain,the traction machines work better than orycontin or dilaudid for aleviating back pain.
Smokin dope does nothing for my back pain other then giving me a better mental state,which then makes it a bit easier to push through the pain,for back pain relief mj is not the answer,you want traction to allow the discs to reshape themselves & high level opiates to deaden the pain.
