Red bumps appearing on skin randomly..help!
Here goes:

I had this red bump on my lower arm, that I thought was a bug bite or a minor skin irritation. Well, the bump flattened, and it was raised. Light red on the outside, with a light pink center that was a dry spot. I've had this thing for almost three weeks..now the lumpiness is gone, but its still a red patch with a light pink center/dry spot.

For the past week, I've been getting these small red bumps on my skin in random spots (specifically, upper arm, lower leg, upper leg) they dont itch or anything. The two bumps that have been there for a week are now again flattened and have a dry patch.

What could this be?

Have you been doing anything different recently, changed washing powder or visited anyone with a dog or cat? They could be bites from dust mites or cat or dog fleas, which can last a long time especially if your skin is pale or sensitive, although these would usually itch. Have you changed your diet in any way? They don't sound like anything to worry about if they are healing themselves, but if you start to experience any other symptoms such as swelling or difficulty breathing seek medical help as allergies can be serious.

Haven't changed my diet, nor soap, my dog doesn't have fleas, and no dust mites as I dust well.

Well thats the thing, their not healing. The one bump has been there for three weeks..I know my allergies so Im doubting that its anything having to do with that. Random skin irritation?

Sorry i couldn't be of more help but hope its of some comfort that you're not alone. I used the same moisturizer for years then one day i used it and got an allergic reaction. For two summers running i got a horrible rash between my wrists and elbows for no apparent reason. For about a year i had a rash round my mouth and then it went away. Totally random! I keep a supply of antihistamines and hydrocortisone cream but even my dermatologist doesn't know what causes these things to happen.
