The Short Answer

The effect is similar to when you hit your funny bone (your ulnar nerve) which can be painful, and cause the pins and needles sensation. People with more common nerve compressions which can be chronic may have diagnoses such as sciatica or carpal tunnel syndrome and experience a range of painful symptoms.
