Introduction
A pimple on the knee that is painful upon touch may be caused by folliculitis, sebaceous cyst, lipoma, or other reasons, and can be treated with medication or surgery. Lipomas are caused by factors such as genetic predisposition and high-fat diet, and may lead to the aforementioned symptoms. Treatment with medications such as Xiaojin Pills or Prunella Vulgaris Capsules can be followed according to medical advice.
A pimple on the knee that hurts when touched may be caused by folliculitis, sebaceous cysts, lipomas, or other reasons. Treatment options include medication or surgical intervention. Specific causes are as follows:
1. Folliculitis
This condition is usually caused by bacterial infection, although in some cases it may be due to fungal infection. During the course of the disease, one or more hair follicles become inflamed, leading to pain or a burning sensation in the affected area. Treatment may include topical application of medications such as compound polymyxin B ointment or mupirocin ointment, as directed by a physician.
2. Sebaceous Cyst
This primarily results from blockage of the hair follicle and sebaceous gland duct, preventing secretions from being discharged properly, which leads to raised areas on the skin surface. It may also be accompanied by discomfort such as swelling and pain. Treatment may involve topical application of erythromycin ointment or mupirocin ointment under medical guidance.
3. Lipoma
Lipomas are typically caused by genetic factors, high-fat diet, and other factors, and may present as lumps similar to those described. Treatment may include medications such as Xiaojin Pills or Prunella Vulgaris Capsules as prescribed by a doctor, or surgical interventions such as liposuction.
In addition to the above causes, similar symptoms may also result from fibromas, furuncles (boils), or cherry angiomas. Avoid scratching with hands and maintain local cleanliness.
