Hi, Im a 31 year old male, Ive had a red oval bruise on my forearm for about a month, I dont know where I could of gotten it from, it doesnt hurt or itch, its been the same colour for weeks its approx. 2 inches long and 1.5 inches wide. Also Ive noticed another two red bruise marks, one on each upper arms and a little larger in size. Not sure what it could be, was thinking ringworm!? but doesnt really look or seem like it could be that, any thoughts>?
Dermatologist conditions are hard to evaluate without seeing them in person. But ringworm (due to a common fungus not a worm) would typically be a red or hot pink oval with a raised outer border. Treatment helps it.
