Why does fingertip numb after spray painting?

When you are using spray paint there is always a chance that you may press the nozzle too hard or too fast which can cause the tip of your fingers to become numb. This happens when you use spray cans for a long period of time.

When you keep pressing the nozzle too hard for a longer period of time the blood fails to reach the nerve and the blood flow gets blocked. The pressure builds up in the area where the blood has been blocked and this leads to the numbness of your fingers.

According to Dr. Raymond Raven at healthtap.com, prolonged pressure on the nerves of your fingertip can cause numbness or paralysis. Depending on the amount of pressure applied, symptoms usually resolve within a few days. If symptoms don’t improve after a few days, you should see your doctor for a checkup.

According to Dr. Jose J Monsivais, this numbness is called Digital Neuropraxia. This is a very likely cause, because there is no blood flow to the nerves. It should resolve in two to three weeks.
