What is red blotches on the skin that come and go?

Answer 1

First, it is very hard to decide what a red mark is ,without seeing it in 3d, and really that means you must visit a GP.

A long term red patch is a result of a scrape or bump, or a burn, a cold burn

or exposure to a foreign substance.

Likely foreign substances are things like

* insect bites - mosquitos, midges, dust bird or cat mites, or bed bugs.. its not common but the lingering effect of a bite might turn into a large red patch after a week or so.

* plants - many plants have irritants in their sap, leaves,stems, and even flower or fruit.

This might also take a week to show up in full.

* chemicals - eg dishwashing detergents are corrosive, paint thinner or paint stripper, and so on.

There are skin diseases that are not caused by an external agents though.

Vitiligo, psoriasis, or otherwise a non-lumpy eczema .. The symptoms so far are not bad enough to be called psoriasis ...

The treatmeants for all are the same.. the skin is sensitive there, so keep the spots moisturised and don't expose them to chemicals or detergents.. even anti-dandruff shampoo can be too strong. Don't dry them out with long showers or baths.

Vitiligo is the symptom of unexplained de-pigmentation in patches of the skin. Vitiligo may be caused by ill-health.. eg malnutrition or lack of vitamin D (you can get vitamin D from certain foods .. or make vitamin D in your skin it by exposure to sunlight.). The patch of light skin may go red because without protection from UV ,and the patch is easily sunburnt. sunburn will then cause the colour to return to the patch, and also Tanning triggers the repair of the skin in general , so exposure to sunlight can be a cure for the spots caused by Vitiligo, psoriasis or any patch of eczema .

Suntanning can make conditions like acne and dermatitis worse.. so be sure its not an infection .

This sounds like it could be hives, especially if they itch. Hives will pop up anywhere on the body, itch (quite severely, at times) then go away, then recur on and off. They can vary in size and shape, from small bumps all the way to large raised welts. While some may not itch a lot, for others the itching can be quite intense at times, causing you to want to scratch your skin off!

The cause of hives can be an allergic reaction, or they can be caused from stress, or there may be no obvious cause for them. The good news is they are easily treated, but you need to see a doctor for a diagnosis and prescription. They are not contagious, so you don't have to worry about anyone else in the family catching them.

Since it is under childcare, the most likely situation is the chicken pox. Most children get it though some are vaccinated against it. The MMR vaccine rules out Measles, Mumphs and Rubella. The chicken pox just itches like lots of little bug bits and causes a fever. It goes away on its on in a week or so. It is a good thing to have young, as the older you are when you have it the more serious it is. There are special "oatmeal" baths that soothe the skin so it isn't as irritated, but it just treats the symptoms and not the disease, as it is a virus. either that or a rash:boomer20:)

Answer 4

does it itch??

Could be from a virus, fever, an allergic reaction...

If you're not feeling ill, try taking a benedryl (diphenhydramine). That should lessen it and stop the itching.

But definitely see a doctor.

Answer 5

They are heat spots. My skin gets them after I take a very hot shower. They are nothing to be concerned about.

Answer 6

It might be chicken pocks or a bite of some sort (spider, ant, mosquito...) :)
