I noticed a bump that is painful underneath a seemingly normal freckle, on my arm. I have freckles and moles sporadically on my body, and I believe most if not all have always been there. I noticed the bump underneath this freckle a few days ago, and noticed when I touched it, it hurt. It feels like a bruise. But, there is definitely a freckle on top that has always been there. Any help/advice is appreciated.
This can be a cyst. Sebaceous cyst is a closed sac or cyst below the surface of the skin that has a lining that resembles the uppermost part (infundibulum) of a hair follicle and fills with a fatty white, semi-solid material called sebum produced by sebaceous glands of the epidermis.It is usually painless but can become painful if infected.Then antibiotics are needed.
