"after a bad stint operation i have been left with serious nerve damage that causes me severe pain daily. i already had enough pain due to bulging discs and curvature of the spine causing sciatic nerve pain. after four operations in a one month period involving instruments being inserted into my ephemeral artery, there is a lot of nerve damage in my right leg now as well. needless to say, it&#039;s difficult to get up each day with intense pain in my back and leg as soon as my mind registers consciousness.beside&quot;regular&quot; daily pain, i also have the occasional &quot;sciatic lock&quot; pain. anyone who suffers sciatic nerve pain knows what i mean.  only experience can convey the pain. after trying every drug on the market, only meperedine works for me!"
