Persistent legpain and burning sensation

I had an ankle injury 5 years ago, and since then, I've experienced recurring swelling and discomfort whenever i engage in physical activities. Over the years, this issue has gradually worsened and I've been dealing with a burning and tingling sensation in my left knee, outer thigh, knee and calf, is a constant problem. It intensifies when i sit, sleep on the affected side or compress these areas, and also feel weakness in the leg, particularly when standing. These sensations often feel like a deep, irritating heat and they can last for extended periods, radiating from hip to the knee and down the calf and ankle. The symptoms have worsened over time and now i am also experiencing same sensations in my right leg. Could this be related to nerve compression or is there another underlying issue. Please some help me as i'm not leading my life peacefully for the past 5 years !
