Local anesthetics inhibit nerve conduction in a reversible manner without altering the nerve. The inhibition appears rapidly and for a longer or shorter duration depending on the products and the concentrations used. The extent of the territory rendered insensitive to pain depends on the modes of administration of the local anesthetic, either at the level of the nerve endings, or at the level of a nervous trunk, for example.
They act at the level of the neuronal membrane by interfering with the process of excitation and conduction. The anesthetic crosses the axon membrane, rich in lipids, in the form of base before taking up a cationic form on the internal face of the neuron where the pH is more acidic.
At this level, there is a blockage of nerve conduction by decreasing the membrane permeability to sodium ions that occurs during the depolarization phase. As the progression of the anesthetic action along the nerve increases, the threshold of excitability increases and the conduction time increases. This is completely blocked from a certain concentration of local anesthetic.
The nerve fibers are unequally sensitive to the action of local anesthetics: they disappear in order: the painful, thermal, tactile sensations.

Answer:
Start by unplugging the garbage disposal. Never work on a drain where the garbage disposal has power.
Use a natural cleaner made from ¼ cup baking soda followed by ½ cup vinegar. Allow it to fizz in the drain for a few minutes before washing it out using very hot water from the faucet.
Allow water to run for a few minutes to clear the clog.
Repeat as necessary.
If the clog remains after using this procedure a few times, use a flashlight to peer into the drain. Sometimes you can see a foreign object in the drain – a bone or utensil. You can sometimes reach the item using a pair of tongs or a needle nose pliers.
Plug the garbage disposal back in, run water and turn it on.
If you still have a block, you can use a plunger to attempt to loosen the clog. If you have a dishwasher, it’s important to clamp the end of the dishwasher line where it enters the disposal to prevent the hose from popping off the disposal nozzle as you plunge the sink drain.
Place the plunger directly over the sink drain, so the plunger completely covers the drain. Add water to the sink, so the lip of the plunger is covered in water. Then vigorously plunge the drain for a minute.
Lift the plunger and check for water flow. If it remains clogged, you can repeat the process a few times to see if you can release the clog. If the clog dissipates, be sure to run hot water for a few minutes to carry away and built up residue.
