Woolly boils, also called woolly boils and tumors, are not clearly conceptualized in Western medicine. The patient’s symptoms are similar to those of typhoid fever, with headache and fever at the beginning, and red rashes on the chest, back, neck and abdomen, which are usually red when they first appear, and turn black after a long time, and these rashes are like nails tightly stuck in the skin, and are therefore called wool furuncles. From the point of view of traditional Chinese medicine, the manifestation of wool furuncle is related to the infection of cold, and the treatment is mainly symptomatic, such as reducing fever, stopping vomiting and relieving pain in the whole body. It is recommended that patients should consult the doctor in time after manifesting the above symptoms, and carry out treatment under the doctor’s guidance, so as to avoid delaying or aggravating the condition.
