What can I do to get on disability someday? Do I necessarily need a long history of doctor's visits?

Here's the deal. Most days my back cripples me. Can't stand for long or my thighs go numb. I have never seen a doctor for it because I figure they will either offer me temporary pain pills, or sugery. I don't want to do sugery because in most cases, it stays the same, or makes the person even more crippled
