Random, strange shaped hives w/pain???

[regenamy]

I've been getting these strange hives on my left wrist (and ONLY my left wrist) for the last month or so. They are extremely itchy and sometimes change shape when I'm watching them. Tiny red dots appear on and around my wrist when the hives break out. Last time it happened (not this particular time) my entire hand and wrist hurt terribly - like someone was stepping on it and turning their heel - a burning, stabbing pain.

I haven't been using anything new - soap, lotion, etc. I've had the tattoo for years, so it's not a reaction to that. A year ago, I got a pretty severe repetitive strain injury on that wrist, and soon after, my veins came to the surface.
I do have fibromyalgia, but I've had it for over a decade.

I've included an image of the latest breakout - a particularly intense one.

Hi,

You could also keep some over the counter antihistamine medications at hand, in case of a sudden flare up of symptoms.

Let us know about how you are doing and if you have any other doubts.

Try to avoid sun exposure and sweat collection and use a medicated sun screen.

Regards.

Thank you for your response.

I'm a full-time student right now - I'm not working. My wrist hasn't been exposed to anything unusual. I don't wear a watch or anything. I don't even wear long sleeves.

When it happens again, I'll just make sure to have some calamine handy. I can't afford to see a doctor - no health insurance, you know.

Thank you again!

Hi,

You could be allergic to some unknown substance or this could be sweat rash or some infection or even eczema or dermatitis.

Do you have any other associated symptoms?

What work do you do? Are your hands exposed to any chemicals or soaps or detergents etc? Do you wear a wrist band or watch at the left wrist?

You could wash the area several times daily and apply calamine lotion at the sites. Take oral antihistamine medications like loratadine or cetrizine for your symptoms.

Try to find out the cause of your symptoms or any factors that aggravate the rash. Consult a skin specialist for a clinical examination.

Let us know about how you are doing and what your doctor advises.

Regards.
