Why is Tinea Manuum/Pedis Itchy?

The itching associated with tinea manuum/pedis (hand/foot fungal infection) is primarily caused by inflammatory reactions resulting from the fungal infection. After the fungi invade the skin, they release enzymes and other irritating substances that stimulate the skin and provoke a response from the immune system, leading to the release of mediators such as histamine. Histamine can dilate blood vessels and trigger inflammatory reactions, thereby activating nerve endings responsible for the sensation of itching. Additionally, fungal metabolites may be recognized by the body as foreign antigens, further activating the immune response and exacerbating the itching symptoms. For the relief of itching caused by tinea manuum/pedis, patients should seek timely medical advice and use antifungal medications under a physician's guidance. It is also important to keep the affected skin clean and dry, and to avoid scratching the affected area in order to prevent worsening of the infection.
