BACK PAIN PLEASE

Hello, ever since I (F19) was a child, I’ve had this feeling where the inside of my body feels like it’s burning, and it interrupts my sleep. I remember when I was around 5 or 6, I had the same feeling and was crying because I couldn’t sleep and it hurt so much.

Now it’s come back, and it feels irritated and uncomfortable. I genuinely cannot find a position to sleep in. It’s like the feeling goes from my back down to my legs. I tried using a big pillow to support my back, but it’s still not helping.

Should I go to a doctor?

Oh, to add on, My back also hurts when I stand up for too long. I don't know if that also adds to the problem.

I'm 19 years old , 5'6 , weight 158.
