Amniocentesis (Definition)

Amniocentesis is a procedure used to draw a sample of the amniotic fluid that surrounds and cushions the baby in the womb. This fluid contains cells that have been sloughed off of the developing fetus. Amniocentesis is most often used to detect genetic abnormalities, though the results can also reveal the baby's sex, gauge lung maturity (if done close to term), detect amniotic fluid infections, or ...Read more

I have a have a sharp needle like pain on the tip of my big toe. I went to the doctor and he used a silver nitrate stick on it. It still hurts.

Toe pain: Do you have anything else other than the pain? It is not clear from your post as to why silver nitrate was used. It's not used for pain. You do need an exam of your toe because without it, it's essentially impossible to arrive to a correct diagnosis. ...Read more

Pins, needles and numbness after cervical discectomy. Is this a big deal?

Pins, needles and numbness after cervical discectomy. Is this a big deal?

Not necessarily: Cervical discectomy is most commonly performed for pain refractory to nonoperative treatment. However, neurologic symptoms are also common. If numbness (medical term is paresthesias), or tingling was present prior to the operation, it may persist indefinitely. If the paresthesias are in the same distribution as the preoperative pain, it may represent residual from the initial problem. ...Read more

I wore a new pair of shoes a week ago and have had mild pins and needles along the sides of my big toes. How long will this last?

Up to 4 weeks: You probably have something called neuropraxia (which means temporary nerve shut down) to the area. This usually subsides by itself if the pressure is off the area and you are no longer wearing the tight shoes. ...Read more

I'm having a pins and needles sensation in my big toes when I'm inactive or in the morning. It only occurs when I put pressure on them. Any ideas?

I mean by narcotized big toes that like having a painkiller needle at interior (not toward other toes) outer side of each, & I have no back problems?

Thanks for: Clarifying. It may be mechanical in nature. Some hints for that would include callous tissue by the toes in the same area, or if the big toe is not straight. If this is the caSe an orthotic might be helpful. Makes sure the shoes are a proper fit. Could be an entrapped nerve. Could be vitamin deficiency, could be signs of systemic disease like diabetes. Still can be back even though no pain there ...Read more

I got my blood drawn and now there's a big bump on my arm where they put the needle. Is this normal? My arm feels numb and it hurts to move it

Should get better.: With any type of trauma there are many events that can happen. Sometimes when the patient tenses up and the needle is put in, the muscles around the area tighten and spasm. It takes a few days for the spasm to dissipate. There are time when swelling develops, like any injury. Icing the area usually helps reduce the swelling. Occasionally a blood clot forms underneath the skin.... ...Read more

After running had sharp needle like pain in big toe and sharp needle pain in heel just in those two spots what on earth?!

After running had sharp needle like pain in big toe and sharp needle pain in heel just in those two spots what on earth?!

Needle pain: This sounds like nerve contusion, depending on the location at the heel, and definitely at the toe. Without a physical exam it sounds like over pronation resulting in the big toe pain. Xrays are certainly also needed to rule out bone spurs and fracture. See your podiatrist for that evaluation and x rays. ...Read more
