Constant Leg Pain: Seeking Opinions

Hey. Would anyone know what’s wrong with my legs? I don’t want to go to the doctor and waste money for nothing. I need opinions. the muscles in the back of my thighs, I forget what muscle but the one the most in the middle, in both thighs, feels like i pulled a muscle there. 24/7. For my whole life. I can’t squat, and I can’t bend down. The only thing that ever helped was a deep massage that really hurt right where the muscle was. I don’t know if this is something serious I should. It feels like there’s a charlie horse in my thighs whenever I try to bend down. I don’t know if this came with my neurological damage, or what. I just need to know if this is something serious.
