Hi ~ I've had a few of these and had basically good experience. One time it didn't go too well, but basically it's been fine.
You must remember that after the myelogram, you MUST keep your head down for several hours or you WILL GET a spinal headache from HELL! Do NOT pick your head up or you'll want to die. This headache is WORSE than a migraine!!!
Some stupid nurse cranked my bed up when I told her NOT to and naturally I got the headache from hell. I screamed & holllered for 4 hours before they gave me ANYTHING for pain!!! And the nurse had the gall to call me a "baby."

If i could have gotten up, I would have tackled that #$$#@#. I told the doctor what she did, and believe it or not, she got FIRED!!!

Hugs, Lee
