unexplained itchy bumps

[Don692]

these ichy bumps have been appearing off and on over a month now. They seem to appear as you itch the area. Mainly located on legs and arms. The bumps are also there even if skin is not itchy. Seems to occur mosty in the evening. Cortorzone 10 relizes the itching for a period, but ichyness returns after a few hours. What could it possibily be. And what can be done about it. Should I be tested for any thing?

Hi.  I'm a 44 year old man, in good shape, workout 4 times a week, I amd a good diet....  but since January 2011, I devleop one per week a red pimple, bump that looks like a large mostiquo bite.  I have seen 2 dermatologists and my GP and they can't seem to find what it is...  we have gone through the "bed bug" extermination process as both dermatologists believed it might be bed bug bites.  These red pimples/bumps occurs usually on genital and under my arm....  once in a while on my leg.  they appear usually one at a time and are very itchy.  I was prescribed cortisone cream and some benadryl-like pill with little to no effect.  I have changed soaps, stopped using fabric-softner...  I'm at wits end.  they tend to occur at the beginning of the week.  I have no known food allergies.  any idea of this could be?

I have a similar condition except i feel an comfortable almost tingling feeling in my nerves or on my skins surface before any bumps appear on my body. Ive have this for about a month now and the doctor has no idea what it is. I thought it may have been shingles at first but apparently it isnt. Taking an oatmeal bath helps relieve the itching for a little bit, but has no long term effect.
