I have some tiny red spots along my upper arm. They do not itch and are nto upraised. They look like the red spots one would find after scratching an itchy area too hard. The spots are even in the pattern of a wide line, rather than evenly around the arm. The only other times I have seen spotting like this on my skin is after the aformentioned tiems of scratching an area of skin too hard. It is not in anyway a common occurence (the scratching or the appearance of these particular red spots).
These spots first appeared a couple of days ago. The previous night I was playign the guitar, which I don't usually do ever, somewhat strenuosly. I noticed my right bicep aching in the way that muscles do when they are being strianed. The next mornign I woke up and my bicep was very slightly swollen and very slightly tender, as one woudl expect from mild muscle strain. The muscle also had the red spots I mentioned. As the muscle strain subsides the red dots are as well. I assume the spots were related to the muscle strain, but I was told that it was unlikely that they were connected despite identical timing of symptom appearance and subsiding.
What are these red spots? Should I be worried or are they something one could expect with the muscle strain I described?
