I also experienced back pain and it feels like the pain run going to my left leg Sur @cmplxty .When I went to the doctor, the doctor found out that it's a nerve problem because I keep sitting down. She prescribed me medicine for that and I drink it everytime I am in pain. The doctor also advised me to have a 30 minutes exercise everyday
Ah that's sciatica, that's not fun! You should look up stretches and stuff online to relieve that, it will really help and exercises! I would stay away from the medication if you can.
