What Are Symptoms Of Post Polio Syndrome?

I had polio at age noine months,1933.When I was eight they did surgery on my left knee(fused the bone) to slow the growth-When I was 13 they used radiation to stop growth in polio leg as it became an inch longer than other.In the past dew years I have severe cellutitus in my polio leg,seems like the circulation to above the knee ceased, may have fried tissues back then.For a few years I feel like I too have the post polio syndrome,as I am extremely weak and tires, doctors can't find a problem for the huge leg with sores nor the weakness.I am 78!
