"Why do I develop painful bumps on my buttocks after sitting for long periods in summer?"

The buttocks, also known as the hips, can develop painful bumps after prolonged sitting in summer. This may be caused by conditions such as folliculitis, eczema, acne, among others. Different causes require different treatments. It is recommended to first consult a doctor, clarify the specific cause, and follow the doctor's instructions for targeted treatment. Detailed analyses are as follows:

1. Folliculitis

This is an inflammatory skin disease of the hair follicles that can occur anywhere on the body where hair follicles exist. It typically manifests as red papules around the hair follicles, accompanied by inflammatory reactions such as redness, swelling, heat, and pain. Treatment options include the use of Mupirocin Ointment, Fusidic Acid Cream, and Levofloxacin Hydrochloride Tablets, under medical supervision.

2. Eczema

Prolonged sitting can lead to elevated skin temperature and a damp environment, potentially causing superficial dermal and epidermal inflammation, manifested as blisters, papules, and itching. In cases of secondary infection, painful bumps may develop on the buttocks. Prevention measures include avoiding prolonged sitting, engaging in regular exercise, and maintaining local cleanliness and dryness to alleviate symptoms. However, in some cases, medication such as Calamine Lotion, Compound Dexamethasone Acetate Cream, and Loratadine Tablets may be prescribed by a doctor.

3. Acne

Prolonged sitting can compress local hair follicles. When sebaceous glands are active, secretions may not be effectively expelled due to compression, leading to the formation of painful bumps on the buttocks. If there are no significant discomforts, observation is recommended. However, for more pronounced pain, treatments like Mupirocin Ointment, Tretinoin Cream, and Erythromycin Ointment may be prescribed by a doctor.
