While you can buy stuff like reagent grade powders on amazon, topical lidocaine does work. The best way to use it is to apply generously, wrap it in cellophane or a similar thin wrap and then leave it for an hour to an hour and a half. You have to use a lot. If it seems like it's all been absorbed add more. Just putting some on and waiting though won't do it. I was experimenting with using dmso and electrophoresis but it wasn't much better. You might also look into veterinary supply companies. Most will require a prescription but some may care less.
Also, do you know what an instapot is? It's an electric pressure cooker and they work great as autoclaves. You just need to but a little rack for inside so the tools aren't sitting in water

what about buying a PMK [pain management kit]?
Dangerous things sells a pmk for around 30$
