I've noticed some dark spots on my lower back, near the spinal cord. Theres no pain or itching, but they started appearing about a month ago, and they seem to be spreading. Im not sure if its something I should be worried about or if its just a harmless skin issue. Any thoughts on what it could be and if I should get it checked out?
Could be a condition called Tinea Versicolor. This is a fungal infection of the skin that can cause discolored patches. I recommend using an antifungal medication such as Clotrimazole cream applied twice daily for 2-4 weeks. Additionally, you can use a medicated shampoo containing selenium sulfide to wash the affected area. Make sure to keep the area clean and dry to prevent further spread of the infection.
