Hi Gigglezzz,
I was curious how you are doing? Something I was concerned about was shingles. Let us know how you are doing and if you're still hurting, we can talk about shingles.
Hi there,
Skin friction caused from clothing, movement or shaving can make the underarm skin susceptible to bacterial attack. Sweat encourages bacterial growth. Allergic reaction, dermatitis are few possibilities. Boils or folliculitis can also lead to red bumps in the armpit. Take an antihistamine for relief in itching. Application of calamine lotion may provide a soothing effect. Seek the opinion of a primary care physician for correct diagnosis. Do write to us again with more queries. Hope it helps.
Best luck and regards!
