Please help, Over this pain!

Sam

Iv been having so much pain in my lower left pelvic area for the longest time. Went to the doctor and they didn’t find anything so I went to the gyno and she didn’t see anything either but I’m going back in a few days. This pain hurts so bad and is starting to shoot down my leg and into my knee. I’m not sure if it happens at a certain time bc I had it every day for a month before! Has anyone ever had anything like this?!
