what is the problem with a pain in the glutes and pain down leg especially after standing up

Hello,
Speaking from my experience on these boards and in my own case, the two main culprits are discs and stenosis. Of course, there are several other possible issues. Many people with injured or degenerative disc issues find their pain mounts or builds the longer they stand. And certain of the spinal openings that our nerves travel through are just naturally compressed in a standing positon. If there is some condition causing a further narrowing of these neural spaces (stenosis) such as degenerative bone growth, disc displacement or disk desiccation (thinning) the effects can be much greater and actual nerve compression occurs. I had severe stenosis at L4-5 and I would have the feeling in my glutes of having done 5 flights of stairs when I was standing still - that real intense lactic acid build-up ache.
I should add that I was later diagnosed as having a severe reaction to a statin drug with associated myalgic damage.
I'm sure others can give you a wider perspective. Good luck - Suzy Q

more likely than not, it is what the other posters said. Sciatica.

you can do a few basic "test" on yourself. these are part of a musculoskeletal exam that would be performed on you.

straight leg raise: lay down on your back, have someone lift the heel of the leg on the side of your pain. if you experience sharp stabbing pain as your heel is raised, it points towards some kind of sciatica. keep in mind to look at how many degrees you can get your leg off the ground (imagine making a 90 degree angle if you got ur leg all the way up) you also have to account for hamstring tightness if you cannot get your leg past say... 30 degrees or so.

but shooting pain is what you are assessing.

also, there is a more sensitive test.

where you sit at the side of a table and hunch over, bring your chin to your chest. now bring your leg up trying to bring it parallel to the floor. this should elicit some form of pain by causing stretch on the nerve roots (assuming nerve impingement)

by bringing your neck/head back up it should relieve some of this pain.

these tests aren't 100% sensitive...

and if they are positive (as performed by a clinician) you would eventually get a MRI and/or NCV and EMG studies.

good luck
