What can I do about my pain medication?

I have been seeing a neurologist for a herniated lumbar disc for a while now, and I have right leg radiculopathy from the disc compressing my nerves in my spine. I have been on hydrocodone 10/500 for almost two years now and have developed a really high tolerance to it (which is normal I know) and I am uninsured, so I can't afford the stronger stuff which most people recommend. I get a 15 day supply of the medication and I usually run out between 10-13 days and get it filled early. My Dr. has already made it clear that I am on the maximum he feels comfortable prescribing, and basically has told me to just quit my job, stop doing housework, and stay on the meds until I can find a job with benefits so that I can have surgery. He hasn't explored any other options (which being private pay I'm not sure what I can afford to do anyways) but when I asked about steroid injections he said that they are too expensive and won't fix the problem. I need help. I am a mother of a 9 month old and a 6 year old, and a nurse. My occupation usually requires me to do the lifting and bending that I am not supposed to do as well as taking care of the kids and helping my husband with the daily household duties. My life has been taken over by pain. It has caused me to not be able to get out of bed some days, to put off grocery shopping, to lose my job, to not be able to play with the kids, etc. I am depressed, and cannot function like I used to. Which interferes with every aspect of my life. I know I cannot stay on the meds forever, nor would I want to because being a nurse, I know what it is doing to my body. But I can't just snap my fingers and have surgery either. Right now my Dr. is on vacation for a week, and the nurse that handles all of my refills is out of the office too. I called to get my meds refilled and another nurse has been really rude to me and told me that there is nothing she can do and I shouldn't have a 15 day supply that it should be a months worth and that I can't get them refilled. This has never been an issue before now. I am going through narcotic withdrawals in addition to severe pain, and dragging my leg around like its dead weight sometimes. I know all the tricks to ease the pain, hot baths, mage, ice & heat, etc. They won't even call me in something for the blood pressure/withdrawal symptoms. I thought about telling her that she can tell my Dr. when he comes back that he has lost another patient. How can they get away with being so hateful when I have to pay an ungodly amount of money for them to tell me to just quit my job and get surgery?
