Have you ever had a medical issue drs just couldn't figure out?

I've had pain in my leg since February. I've had x-ray, ultrasound and MRI and nothing is visibly wrong. The specialist orthopaedic dr said he was stumped as to what could be the issue. I basically have to hope it goes away or gets worse 😔
