Patient discussion about herniation of intervertebral disk.

Q. I have a low back pain that radiates to my leg when i pick up stuff. Is it a disc herniation? I am a 43 years old bank teller. During the past 5 months I've suffered from a low back pain. The pain is not very strong, but it gets much worse while doing physical activity. When i walk or lift heavy things the pain is even stronger, and it radiates to my left leg. Can it be signs for disc herniation?

A. You can't tell for sure that your symptoms are due to a specific disc pathology.
When i had similar symptoms i went to the GP and he told me to lay down on your back. Then he slowly raised my left leg while the knee is kept in extension.
He said that If raising the leg over 60 degree exacerbates the pain its very likely to be disc herniation. But you should go to your GP and have him examine you.

Q. do you know of a good gastro doctor in staten island ny. I have acid refex so bad cant sleep, or lay flat.. years ago was told I had a hiatus hernia, and would only have fLare ups once in a while, have taken nexium for years, and it worked, but not anymore.. I really need to find a good doctor to test me again.

A. Try www.ucomparehealthcare.com/drs/new_york/gastroenterologists/Staten_Island.html for a directory of gastroenterologists in your area. This is only a website I've found - haven't tried it and I have no idea how good or reliable it is.

Take care,
