Are these hives?

 I'm really confused, I keep getting these things on my face, probably on average about 5-10 a week of them, sometimes one or two at a time, sometimes all together. They're a bit of a cross between a smallish pimple and a large insect bite. I'm male and in my mid twenties.

Here are the features (sounds like I'm selling a car!):

raised bumps

they don't hurt

sometimes they're a bit itchy

if you scratch them lightly with a finger nail it takes a tiny piece of skin off the top, revealing a small red wound, the bump quickly begins to go down. You can also lightly put a pin in them, just enough to break the outer layer of skin.

just out of curiosity i sqeeuzed one to see what was in it, a little tiny drop of blood reluctantly came out.

i've had them for several months, in which time they've moved away from my ears a bit towards my cheeks, although they come up smaller than what they did, they are more frequent now, at first i thought it was a fish oil supplement that was causing them as it seemed to subside a bit when i stopped taking that, and the same for a zinc supplement. Now i take neither, and like i say they're much smaller but i can't hardly go 48 hours without them.

I'd be really really greatful for any advice, thoughts, anything! It's really playing havoc with my anxiety disorder! Mark.

Just the fish oil which definately was having some bad effect,though i stopped that around a month ago. It's too hard to tell if they're near hair follicles, i guess there's a higher density of them coming up where i'm more hairy (towards the sides of my face). I've not really had any notable allergies, and have always used any detergent etc, except for always using a clean and clear brand wash, for acne.

Thanks for your reply Red, I'm going to give moisturising a try (a totally foreign concept to me being male and all!) if that doesn't pan out I'll seek medical advice like you say. :)
