In fact, this disease is inextricably linked with personal physique, mental state and autonomic nervous dysfunction.

The general state is that papules and blisters as big as millet appear repeatedly in arms, elbows, palms and other parts. There is no obvious inflammation around, and the blister wall is thick, which shows that the blister fluid is transparent at first and then becomes turbid. After three days, the liquid will absorb itself and dry up to become desquamation, and the pink new skin will be exposed again, and the fingers will form a chapped shape when flexed and stretched. Patients will feel itchy and hot in the affected parts. Summer is particularly easy to grow hair because it is humid and sultry.

Second, eczema

Do not wash with alkaline soap or detergent. Do not tear or puncture the blisters. Go to the hospital for examination and treatment.
