Achillies lower back ?

It's been 3 weeks since my back put me on my knees. There are 2 herniated disc pushing on my sciatic nerve. Causing pain, tingling and partial paralysis . being on the bike is the most painless position. I've raced with this condition and did well. The real pain comes at night. I have not slept in weeks and pain killers have little effect on pinched nerves. It doesn't help that I'm between insurance right now. There's a quick n easy surgery that can remove and restore practically over night. But they need $5000 up front. Until then I'm a man with a bullet in his back.
