Ive noticed dark spots under my armpits, and the skin there seems darker than the rest of my body. The upper part of my armpit has these dark spots, and theyre the same color as the surrounding skin. Is this something to be concerned about or can it be treated?

To manage recurring hives on hands and feet, consider consulting a dermatologist or allergist to identify underlying causes, and explore alternative treatments like immunotherapy, sublingual immunotherapy, or medications like montelukast or cyclosporine, while also maintaining a symptom journal and avoiding potential triggers.
