Question: Rash to my hands, arms and neck
|nursylori - Sat Feb 23, 2008 2:58 pm||
I noticed a week ago that my upper arms just above my elbows began itching. There was no noticeable rash at that time. A couple of days later, I woke up with intense itching to the tops of both of my hands and noticed a flat, red, blotchy rash on them. The next day I woke up with itching to both forearms and the same rash appeared. It is now a week later and the rash is still there, but it is flat in some areas and slightly raised in others. It is only on the tops of my hands/fingers, forearms, upper arms above my elbows and my neck/chin area. I've been putting Cortizone cream on it, but it hasn't helped. Today, I started applying Benadryl cream. I have not taken any new medications nor eaten any new foods. I am using the same soap, shampoo, lotion, laundry detergen, fabric softener and makeup that I've used for a long time. I am baffled by this and the itching is driving me nuts at times. Here are some picture I took today.

The cause of a rash can be very baffling. An allergic rash would look and act much like what you describe and it is possible to develop a hypersensitivity (allergy) to something at any time so it does not have to be something new. It can be a food you have eaten your whole life, then suddenly you can't any more. Latex is an example of this. Some people develop a latex allergy only after years of latex exposure through gloves, etc. We don't know why the body suddenly sees something familiar as foreign and threatening enough to cause a reaction.
There is also contact dermatitis, where some irritant touches the skin and causes a reaction. Sometimes you can also get what is called an ideopathic dermatitis. This just means we don't know and probably never will know what caused it and can only treat the symptoms.
If the topical hydrocortisone doesn't help, you may need to have a prescription steroid which is taken only for a short time and tapered off gradually. Symptoms can also be relieved with an antihistamine such as Benadryl. Caladryl lotion or aloe vera can also be soothing to the skin.
The bottom line is that if it doesn't just go away on its own you may need to see a dermatologist.
