I am having a lot of bad leg pain around the knee, upper thigh, and above my ankle on my driving leg, especially when i am driving. lasting weeks.

Lower extremity pain: First of all, we need to know if there is a history of trauma. If there is trauma, you need x-rays and possibly an MRI and blood tests. If there is not trauma and this happened spontaneously, there are a few conditions that have to be ruled out. Pain has to have a source. Do you suffer from low back problems? Are you active in sports? Do you have circulation issues? We need a better history.
