Orange Spots on 6-line Wrasse

[Endevor]

This morning I noticed some strange orange spots on my Six-Line Wrasse and he was also sleeping out in the sand in the corner of the tank. It was really early when I saw him though and I didn't turn on the tank light until much later after my morning army PT. When I got back, he seemed fine and was swimming around all over the place, ate fine, and even as I type he's doing laps around the rocks. I've seen some posts on other forums with similar problems, but none have an answer. I think one post somewhat came to a conclusion that he brushed up against a rock and accidentally hurt himself and he was fine a couple days later, but mine seems a little worse than they described. Attached are some pictures I tried to take of him and his spots. Does anyone know what this might be and what can I do to help him out? Medicine, etc.

Thanks
