Shoveling Hand Swelling What Causes Swelling, Severe Itching And Pain On Hands And Feet, Lasting 1 Or 2 Days?

What causes swelling, severe itching and pain on hands and feet, lasting 1 or 2 days? - shoveling hand swelling

Several years ago I hurt my hand digging with a shovel. Hula, pain and itching bad for 2 days and then left. Since then, every time I put my hands repetively (with scissors so much), or standing for long periods with the hand or foot swelling, and itching so bad that I have with the hand or foot. In one or two days he goes. My doctor has tried (unsuccessfully) for arthritis, but I began to doubt his diagnosis. I have a few years ago for nail fungus is cleared up, but I wonder whether it is a fungus loose somewhere on my body. Has anyone any idea what could be?
Thank you.
