I am receiving treatments for lower back pain - nothing major, just looking for improvement. I am also having a problem with acute pain at the back of one knee. The pain never completely goes away and most of the time is tolerable. It does, though, go through patterns of severe pain at times, which mostly happen after periods of either sitting or laying, when I stand up. 99% of the time the only discomfort is just at the back of the knee, but occasionally the pain will spread half way down the calf and half way up the thigh. It's been checked out by my doctor, I've had it x-rayed, and nothing has been detected.
I have just read some information about Sciatica and was wondering if Sciatica can cause symptoms similar to mine.
