ImmYazmin,
As I mentioned in a post to another member, it is possible to develop pain from an IV site.
Around the wrist, the most common place to start an IV is in the vein on the radial side of the wrist, just a little proximal to the thumb. This is a large vein and fairly consistent, so most providers will go for it first.
But, there is a fairly large skin nerve right in that spot that can be injured. The vein also sits right over the first dorsal compartment of the extensor tendons.
So, if the nerve is injured, a neuroma can develop. A neuroma usually causes an electrical shock type of pain when tapped.
If the first dorsal compartment gets irritated or inflamed, it is called a tenosynovitis. In this particular place, it is called DeQuervain's.
But, if the IV was placed somewhere else, such as the back of the hand, on the forearm or in the antecubital fossa (front of elbow), then other structures may have been injured or irritated.
But, if the pain is located on the thumb side of the wrist and it hurts to bend the wrists to the thumb side, then you most likely have DeQuervain's.
This disorder is actually very common in pregnancy and for about 2-3 years after the baby is born. During pregnancy, it is due to the fluid shifts around the body and swelling in the wrists and hands. After delivery, it is usually due to overuse and how infants and toddlers are picked up. Usually, toddlers are picked up with the parents's hands under the child's arms, thumbs pointed up in the air. This causes the tendons that go through the first dorsal compartment to be stressed.
DeQuervain's is usually treated with short term immobilization of the thumb and wrist. New mothers often have trouble wearing the splint, because it can interfere with handling the baby. But, if you can get a thumb spica splint or short opponens splint, the immobilization will help with the discomfort. A regular wrist splint will not work, because it does not stabilize the thumb.
Antiinflammatory medicine, such as ibuprofen or naproxen, if you can take it, is often helpful with the inflammation. But, if you are breast feeding, be sure to ask your pediatrician if the medicine in okay.
Ice packs when the discomfort is really bad usually helps. At night, a hot pack is usually more soothing. So, either ice or heat is okay.
But, if these measures do not work, then you may have to see a physician. Sometimes, a hand surgeon will order occupational therapy for the condition, to include iontophoresis or ultrasound over the compartment. But, if this does not work, then an injection of steroids is sometimes used.
Hope your wrist feels better. Have a great time with your new little one.
Good luck.
