Summer underarm pain and redness may be due to sweating inflammation, intertrigo rash, lymphadenitis and so on.
1. Sweatitis: hot weather and mental stress can easily cause excessive sweating in the armpits, and the humid environment may lead to Staphylococcus aureus infection, which can cause skin infections and lead to the symptom of painful red armpits in summer.
2. Interstitial friction rash: it is an inflammatory skin disease, mainly due to local humidity, high temperature, lack of air flow, sweat stimulation and other skin problems, which may lead to secondary bacterial and fungal infections, which can cause summer underarm pain and redness.
3. Lymphadenitis: Underarm lymphadenitis can cause lymph nodes to become congested, enlarged and painful, which may also manifest as symptoms of summer underarm pain and redness.
There may be other reasons for the redness of summer underarm pain, and you need to go to the hospital in time for examination, clarification of the cause of the disease, and symptomatic treatment.
