Not sure exactly where in texas you are, but there are MANY forms of advanced pain managmemnt therapies from implanted pumps that deliver IV meds, intrathecal(directly into the spine), pure liquid morphine, fentanyl pops, your doc is NUTS and you need a consultation with a PM doc who specializes in oncology PM...PM me & let me know where you live & maybe we can come up with some options...the OP route isn't going to provide you the relief you need, you need serious Pain Management...and it's available...and they need to treat your pain till it's way beyond just tolerable!!!!
