So I Got Shot Some Years Back As A Teen.

So I got shot some years back as a teen. I currently still have the bullet still in my leg but it's been traveling over the year's as the doctors said it would. But now I can feel it closer to the surface but it's located in the back inside of my right thigh and I feel like it's causing some uncomfortable pain in my general leg region sometimes in my hip,back of my knee or just in my thigh period. I guess what I'm asking is is it possible for this lodged but yet traveling bullet to cause complications within my leg
