Back surgery for a better life

My back problems started in 2004 with lower back pain and dyesthesia (burning muscle pain). Over the last 10 years, it has continued to progress to where I am now having trouble sleeping for longer than 2-3 hours at a time, I have loss of feeling in my right calf, foot, and toes along with minor numbness in other areas. The pain has worsened now, and the other treatments are no longer working. I have had every other injection and procedure possible including 2 RFAs.

So now, my doctor has said it is time for a Fusion of my L4 and L5 areas. I am fine with this (although a bit nervous), however I don’t have the money to cover the out of pocket costs and the lack of income. My out of pocket cost is $6000, and my loss of income will be over $6000. I have three kids in college, a house, and am only a teacher. So this is quite significant.

I would sincerely appreciate any help I could get. I have borrowed some money to help but will need it to pay back and more just to be able to live. Thanks so so much!

Attached are my imaging results so you can verify my information (and also see the mess my back is in!)
