I've been dealing with pain for a couple years and I'm only 22. I went for help and my PT tells me that I have weak glutes which is causing misalingment within my body. My right leg is tight and I have pain mostly in my right knee. Sometimes I feel weakness and tingling in my leg also. I've had lower back pain but it hasn't really bothered me as much as it has in the past 2 months. For example, when I bend to pick something up I feel pain right in the middle (close to my buttocks area). It will radiate to the sides which can usually be fixed by a massage or foam roller.
This lower back pain isn't constant and will go away for a while however. I've also gotten a bone scan which showed nothing.
