My right knee hurts. it always has. even when i was just a child. i can't fold my legs for too long. reason?? now that i'm obese, it hurts even more!

Be seen: You would really need to be seen and examined and probably undergo some testing for an accurate diagnosis as there are multiple possibilities, from an undiagnosed inflammatory arthritis to some type of congenital problem. There are so many pisdibilities. On top of that, obesity can aggravate an underlying knee problem as well and should be treated aggressively.
