“Xiaojiu, recently I have some small blisters on my hands, always itchy, do you know what is going on?”
“Small blisters on the hands? It could be sweat blisters or hand moss.”
“Huh? Then which one is it?”
In August, the weather is getting hotter and hotter, and skin diseases are starting to move, so if you don’t pay attention, various skin diseases will come to you. Among them, sweat blisters and hand moss are also many people’s “old friends”.
So, if you have a small blister on your hand, how do you distinguish whether it is sweat blister or hand moss?
A. Small blisters on the hands, sweat blisters or hand moss?
The hot summer always gives people a sense of “hot and humid”, especially the hands always appear small blisters, very itchy and uncomfortable, scratching will also be accompanied by molting performance, in fact, this is the problem of herpes sweat. In simple terms, herpes sweat is a blistering eczema that occurs mainly on the lateral edges of the fingers or toes and the palmoplantar area.
In addition to this, there is another hand skin disease that is very frequent, and that is ringworm. Ringworm is a contagious skin disease caused by a fungal infection that usually starts on one hand and gradually spreads to the other hand because it is not treated in time and develops as the disease progresses.
Many people confuse herpes sweat with ringworm, but there are significant differences between the two skin conditions.
First of all, herpes sweat occurs mainly on the palms, fingers, or back of the hands, and is mainly characterized by red spots and small blisters with itching and discomfort, and after the blisters have dried up, there is obvious molting and cracking of the skin, which can be painful. Tinea capitis occurs mainly on the palms of the hands and usually develops unilaterally before developing bilaterally over time.
Secondly, it is likely that the symptoms of tinea capitis will diminish or disappear after a period of time. In contrast, tinea cruris does not suddenly disappear without consistent use of antibacterial medication.
Finally, both herpes and ringworm can get worse or come back easily in the summer, but in the winter, herpes is less common, while ringworm persists in the winter.
