I have a rash on my hand that comes and goes. I, m thinking its a fungus. It itch at times. Could u advice me?

Difficult diagnosis. Rashes or other skin conditions are very difficult to diagnosis accurately without actually seeing (and feeling) the rash. Although an itchy rash that comes and goes can be a fungal infection, there are many other possibilities as well. Best to see your family doctor or dermatologist to narrow the diagnosis.
