Question: Very itchy rash mainly on forearms

 GreyKitten - Tue Mar 24, 2009 2:36 pm

I went on holiday at the beginning of December and got quite a lot of mosquito bites. After we came back the 'bites' kept appearing, I thought I'd packed a mossie in my luggage!. Anyway, since then it's got steadily worse and is changing a bit.

I now have a mixture of - 'normal' hives; bright pink patches which look flat but feel bumpy; clusters of tiny, hard and extremely itchy bumps which are either skin coloured or red (usually due to scratching); a few small, hard and well-defined fluid filled blisters which appear singly or in pairs on red patches, usually on the outer edge of my hands. Whichever area is currently the most itchy is also warm to the touch.

Most of this is on the outer sides of my forearms, with the small hard bumps occuring mainly within a couple of inches of my elbows. It comes and goes on my fingers but sometimes I get the 'pricked by a hundred needles' feeling over the backs of my hands. I have a few outbreaks of regular hives on my lower legs and feet, sometimes I get blisters or bumps on my feet but they’re pretty transient. I also get a lot of large hives on my bum!! Occasionally my back goes crazy and I get needle-pricking and itching so bad that it makes me flinch - this usually only lasts for an hour or two then dies down.

When the larger bumps actually go they leave either a purplish bruise (which doesn't seem to fade) or a light brown discolouration and they still itch from time to time (not fair - when they're gone they should stay gone!). I can also feel lots of bumps under the skin which aren't visible.

Anything touching the skin on my forearms makes me itch, it feels like I've just had a hair cut and you get the little hairs fall on your arms!

I've always been prone to hives but never anything like this! My husband has no rash at all so I don't think it's bugs. The only thing 'out of the ordinary' is that the usual mouse infestation that we have at work seems to be heavier than usual. However, I do have a stressful job and my marriage is, at times, 'volatile'.

I'm 54, female, overweight, not on any medication, only known medical condition at present is hypertension. I'm taking an 'over-the-counter' antihistamine daily but it doesn't seem to have much effect.

If this sounds familiar or anyone has any ideas I'd be so grateful, this is really beginning to get me down...........

User avatar Hello,
Sometimes hypersensitivity responses require a prescription steroid-based medication to heal so if several days of antihistamine has not helped you should see your doctor.

You may be having ongoing contact rashes rather than just a prolonged reaction to the initial offender. Switch to mild, non-perfumed soaps, lotions, detergents, etc. to see if it makes a difference. You could also try a mild over-the-counter hydrocortisone ointment or Caladryl lotion too.

Good luck

User avatar Hello,
Do you have a pet which might have brought fleas? Scabies also affects many people in all walks of life, particularly in close quarters. If so, diligence in household extermination is needed. All linens must be washed in hot water, vacuuming should be done extensively and bag thrown out afterward.

The extent to which any of these conditions bothers you can vary depending on your sensitivity. Some people hardly notice; while others react severely with a hypersensitive response.

To get an accurate diagnosis you probably need to see a doctor such as a dermatologist. The intense itching may be relieved with antihistamine medication.

Good luck.
