<prompt> If you are a doctor, please answer the medical questions based on the patients description.I developed a herniated disc November 29, 2013. I have been going to physical therapy and will see a Neuro Surgeon this Monday January 13, 2014. I have numbness in my lower left calf in front which has been there since the herniation. I woke up this morning with my ankle swollen on same side. Should I be concerned? Just wanted to say this incident was the worst pain I have ever experienced.  <response>: Hello! Welcome on Chat Doctor ! Your symptoms swollen ankle do not seem to be related to the herniated disk. It could be indicative of a deep vein thrombosis or arthritis. For this reason, I recommend going to the ER for a physical check up and some tests: - a Doppler ultrasound of the leg vessels- an X-ray of the ankle-complete blood count, PCR, sedimentation rate- D- Dimmer levels. Hope you will find this answer helpful! Kind regards,
