Whether you are donating blood or getting blood tests, when cold, hard steel mixes with delicate inner tissues and veins, many things can go wrong. If you experience unusual or prolonged pain after getting blood drawn, you may be at risk for a rare but serious condition.


Under-trained or careless technicians might cause damage to your veins, tendons or nerves with improper needle insertion. Make sure the technician is certified and stop the procedure if you feel intense pain.

Having blood drawn requires a larger needle than blood tests, causing a higher rate of donor injuries. Nerve damage and chronic pain are the most common symptoms.
