i have brownish slightly reddish spots on my inner elbows about a few millimeters diamater, not perfectly round and some may have possibly merged into larger shapes, i may have similar sort of marks along my body, however less pronounce and the colour is more even on my skin, with a heavy amount merged on my back, i also have red streaks on my inner biceps from the shoulder only continuing for about 5cm towards my elbow which im not sure wether their related or stretch marks.
