The answer to this day: not much. "From waking up to going to bed, the pain was, and still is, always there. It is caused by a nerve in my left leg. But what exactly causes this nerve pain?

One day, I noticed a pain in the back of my right leg ... After the ER doctors sent me back to get an ultrasound of my legs, I laid in my hospital bed thinking of all sorts of things.

My hip/leg pain started after I spent my days walking and climbing stairs in Paris. (I walked 20 kilometres one day!) I rested during the evening and took ibuprofen before going to bed.
