Welcome to our little group. Sciatica can cause the symptoms that you are having, which is usually caused by a flare up of the sciatic nerve. Did you lift something heavy lately the wrong way? Is this pain constant or only when you walk? What helps the pain? What makes it worse?
I'm a bit confused, because DDD and stenosis can not be diagnosed by xray nor by testing your reflexes. Bone spurs that effect the spinal canal would have to be seen on another test, rather than an xray.
DDD is by itself usually not a problem, since all of us have it, some worse than others but if you are over the age of 21, you will have some drying out of the discs, it's perfectly normal for most people and it usually doesn't cause pain. That's not to say that it can't for some people but they are usually older and it's due to more drying out of the discs as we get older.
Do you know what pain medications they gave you? It would help to know what they are, so that you can tell the pain management doctor if they surgeon refers you to one.
And the muscle relaxants as well.
The appointment with the surgeon, did they make it for you? That's rather unusual , do you mean they gave you a referral? If so, make sure that he or she is a board certified spinal surgeon, not a general orthopedic surgeon.
Try ice and heat in the meantime. You would be surprised how much they help relieve muscle tension and ease inflammed nerves. The PM doctor will most probably offer injections into the spinal canal to ease the inflammation using steroids. And some anti inflammatory medications to ease the inflammation and pain.
I hope that your appointment is soon and you find some relief. You can also purchase those heat wraps at the drug store, they work really well and last for anywhere between 6-12 hours and those will help alot in the meantime.
