Is this psroriasis?

[D Foster]

As Fred say's it's very difficult to tell, as you say they do look like bites from something like animal fleas especially as they are on you legs however I would go and see you GP as soon as you can because what ever it is needs sorting as soon as you can.
Welcome to the forum , don't take this the wrong way but I hope that it's not P so we won't see you on here unless of course you pop on to say hello .
