Is the hulk sick or does he have a skin condition?

The Hulk is not sick nor does he have a skin condition; rather, he is a fictional character from Marvel Comics who transforms into the Hulk when he experiences intense anger or stress. This transformation results in a drastic change in appearance, including green skin and increased muscle mass. The Hulk's unique physiology is a product of gamma radiation exposure, which gives him superhuman strength and durability rather than being indicative of a medical condition.
