"i have chronic severe back pain from an injury at work.  fractured my t12 and messed up my lower back and a pinched nerve.  i have been through physical therapy, nerve blocks.  i am now on oxycontin 10 mg 3 x&#039;s a day, vicodin 5/500 for break through pain (i take about 4 in 24 hours), neurontin 300mg 3 times a day and paxil for depression.  before being placed on all of the above my pain level was at 8-9. now my pain level is 6-7 except if it rains or is cold then it&#039;s a 9.  i&#039;m still unable to do anything.  pain increases with any activity despite the medicines, plus i feel faint when i stand up, brain is foggy, poor memory. hear common noises that i mistake for something else like singing or talking."
