Emergency!
One night, the arm covered with blisters, did not think much, the next day began to bring thick blisters more, but not itching.
Thinking that there was an Imm1 immune system defence capsule at home, I immediately took four capsules a day for six days, getting better and better every day, and now it has scarred.
It turns out that it is caused by decreased immunity, and oral Imm immune defence capsule is really strong.
