Why is it when my hands are inflamed, hot or dry the soap seems to disappear before i come to rinsing them? i saw the soap had disappeared from under my nails and top of hands just before i was going to rinse. sometimes happens whilst im lathering?

Its doing its job: Oil and water cant mix and separate into layers. A molecule of soap has a tail that can penetrate into or mix with the oil and a head that will dissolve in and be washed away by water taking a piece of grease with it. Without the oil the soap molecule orients its tail away from the water forming suds or bubbles. If there's grease the suds will disappear with the grease into the water.
