This is the third occurrence. The first lasted a few days, the second, about six weeks. This one has been going on for about four months now and seems to be getting worse. Shooting pain starting in the right buttock and travelling down the side of the leg into the calf. I've had MRI's taken and according to the neurologist and neurosurgeon there isn't anything that would account for the extreme pain. I've had an EMG and there's no nerve damage. Currently, when I wake in the morning and stand on my feet, the pain is excruciating. Sitting immediately helps to make the pain just bearable. I then take a couple of Excedrin which seems to take away most of the pain. I try to take the Excedrin only in the morning when it is the worst. I can make a good portion of the pain disappear if I lie face down on the bed and wait. It will start to subside but doesn't completely disappear. It's much worse in the morning, tapers off during the day, and gets worse at night. I've been told that if it was sciatica, I wouldn't be able to sit for any length of time but that doesn't seem to be the case. When this last bout started, work and exercise made it disappear completely. That doesn't work anymore. Any suggestions?
