Woolly boils can be detected by picking the purple-black dots at the sweat pores in the precordial area and the back of the body, or by pressing on them.
1. Needle picking: Generally, a needle can be used to prick the purple-black dots directly. If there is no bleeding and a wool-like object can be picked out, then it means it is a wool furuncle. If only bleeding is seen and no wool-like material is found, then it is not a wool boil.
2. Pressing: Usually, a needle and nose can be used to press these purple-black dots. If there is a hard feeling of resistance during the pressing process, and the pressed area appears to be sinking or not being able to rise up, then it means that it is a wool furuncle. If there is no hard resistance during the pressing process, and the pressed area does not sink or fail to rise, then it is not a wool furuncle.
If the patient has a wool furuncle, he should go to the hospital in time to have his condition clarified with the help of a doctor, and then have it treated in a positive way.
