For most people with a herniated disk, low back pain is the initial symptom. This pain may last for a few days, then improve. It is often followed by the eventual onset of leg pain, numbness, or weakness. This leg pain typically extends below the knee, and often into the foot and ankle.

Corundum is used more as an alloy to make advanced versions of other armors, such as banded-iron armor and plate armor.orundum ore is smelted with iron ore to make 1 steel ingot, so don't go crazy smelting all your corundum ore into corundum ingots unless you know you don't need steel (doubtful as some advanced armors and weapons require a steel ingot as well). To mine ores, you must have a pickaxe in your inventory.
