Too many attempts to draw blood result in a hematoma (blood trapped under the skin’s surface). This is accompanied by pain and numbness, which turns into permanent nerve damage. Dysesthesia (burning sensation) and paresthesia (a “pins and needles” sensation) may also occur.
Can you get nerve damage from having blood drawn?
A more serious injury from a blood draw is nerve damage. There are bundles of nerves close to your major veins, and if one of those nerves is nicked or punctured by the phlebotomist (the person drawing your blood), you could experience the following: The feeling of an electric shock during the procedure.

Can you hit a nerve during a blood test?
Rarely, the needle will hit this tiny nerve on the way into the vein. This may cause a short, sharp electric-shock type pain. This may be all that happens; however in some cases tingling type of pain may persist for one to four weeks, as the nerve heals.
What is the signs of nerve damage?
The signs of nerve damage include the following: Numbness or tingling in the hands and feet. Feeling like you’re wearing a tight glove or sock. Muscle weakness, especially in your arms or legs.
Which vein site has an increased risk for nerve damage during venipuncture?
Risk of nerve damage is higher especially when the cephalic vein is punctured in the lower part of the cubital fossa, making it a dangerous area for venipuncture.
Why does my arm hurt so bad after blood draw?
This is completely normal and should not cause you any concern. Although bruising can be unsightly, it should resolve over the next few days without intervention. Very rarely, pain or discomfort in your arm, hand, or fingers can indicate inflammation of the arm, a tendon or nerve injury, or the puncture of an artery.
What is the most common complication of venipuncture?
Results: Minor bruising and hematoma were fairly common, involving 12.3% of venipunctures, with minor bruising being the most common reaction. Serious complications were observed in 3.4% of patients. Diaphoresis with hypotension occurred in 2.6%. Syncope occurred in less than 1% of patients.
Why are valves problematic in blood samples?
Hitting a valve during access can cause a vein to be blown if the valve flap were to obstruct the flow of the solutions being administered, and this can cause the patient pain.
Where should you not draw blood?
Do not use the tip of the finger or the center of the finger. Avoid the side of the finger where there is less soft tissue, where vessels and nerves are located, and where the bone is closer to the surface. The 2nd (index) finger tends to have thicker, callused skin.
Can a bad blood draw cause permanent damage?
Medical professionals train so that they can easily and accurately insert a needle into someone’s vein to draw blood or give a drug without damaging the nearby tissue.
Do blood tests damage your veins?
Every time you have a blood test or an IV line in your arm, it damages the veins. Repeated blood tests cause progressive scarring to your veins. Some people, especially those with kidney disease or diabetes, need a lot of regular blood tests, and their veins can get damaged over time.
What is the median nerve?
The median nerve provides motor (movement) functions to the forearm, wrist and hand. It also sends touch, pain and temperature sensations from the lower arm and hand to the brain. A pinched median nerve can cause carpal tunnel syndrome.
Why do I feel weird after getting blood drawn?
The most likely reason you felt sick to your stomach when you had your blood drawn is that your body was having a vasovagal reaction. This is a physical response from your nervous system. It can be triggered by seeing the needle, seeing your own blood, or just feeling anxious about the whole thing.

What happens if nerve damage goes untreated?
Left untreated, nerve damage may worsen over time. It can sometimes start in the nerves farthest from the brain and spinal cord — like those in the feet and hands. Then it may move up into the legs and arms.
Does an MRI scan show nerve damage?
An MRI may be able help identify structural lesions that may be pressing against the nerve so the problem can be corrected before permanent nerve damage occurs. Nerve damage can usually be diagnosed based on a neurological examination and can be correlated by MRI scan findings.
Can a needle cause nerve damage?
Several mechanisms are associated with injection-related nerve injury; direct needle trauma, toxic effects of injected agents on nerve fibers and surrounding tissues, nerve compression due to hematoma or edema formation, and so on. Among them, direct needle trauma is the most frequent factor.
Can anything be done for nerve damage?
Sometimes a section of a nerve is cut completely or damaged beyond repair. Your surgeon can remove the damaged section and reconnect healthy nerve ends (nerve repair) or implant a piece of nerve from another part of your body (nerve graft). These procedures can help your nerves to regrow.
What happens if you hit a nerve with a needle?
When a nerve injury is caused by a needle, most patients report immediate pain at the time of injection,11 as our patient did. Neurological sequelae can range from minor transient sensory disturbances to severe sensory disturbances and paralysis.
