Two hard lumps have developed under the armpit.
Two hard lumps appearing under the armpit may be caused by swollen lymph nodes, folliculitis, flat warts, or other reasons. Treatment should be based on the specific cause. Details are as follows:
1. Swollen Lymph Nodes
This is usually a reactive proliferation caused by various injuries or stimuli, which may result in hard lumps and pain. Under medical guidance, medications such as Yanlixiao capsules or thalidomide tablets can be used for treatment.
2. Folliculitis
This is typically caused by friction from external substances or bacterial/fungal infections leading to hair follicle damage. Inflammation may lead to the aforementioned symptoms. Following a doctor's advice, topical treatments such as compound polymyxin B ointment or mupirocin ointment can be applied.
3. Flat Warts
These are usually a viral condition caused by human papillomavirus (HPV) infection, transmitted directly or indirectly. Skin lesions mainly appear as small, grain-sized hard bumps. Under medical supervision, topical medications such as isotretinoin erythromycin gel or fluorouracil ointment can be applied.
In addition to the above causes, such lumps could also result from sebaceous cysts, lipomas, fibromas, etc. It is recommended that patients seek timely evaluation at a reputable medical facility, wear loose and comfortable clothing, and maintain good hygiene through regular changing and washing of clothes.
