Why does the fingertip feel numb after spray painting?

Spray paint can nozzles are notorious for being tiny, easy to break, and irritating to your fingers.

When you press the nozzle too hard and too long, the blood fails to reach the nerves, and the blood flow gets blocked for a while. Eventually, this pressure builds up and blocks the receptors in your fingertip responsible for feeling pain and touch.

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

According to Dr. Jose J Monsivais, severe cases of this numbness are called Digital Neuropraxia, which is caused by the reduced blood flow to the nerves. It should resolve in two to three weeks.
