I have a very itchy rash on legs and arms. Raised bumps which scab over due to scratching. I've recently travelled to the US (stayed in hotels).

Many answers

Rash
You should see a dermatologist re. this problem. Some of the potential answers include flea bites (as more and more hotels are allowing pets to be in the room), bed bugs, etc. By the way, how recent is "recent" .

Dr. Johnnie Alston answered:

what causes an itchy rash with little bumps on top of my feet and redness on lower legs? Also bumps are not itching anymore, now they are dry bumps.

Allergic reaction

Leg
Usually rashes on the top of your feet are casued by some type of allergic reaction or contact dermatits. With your lower legs involved I would rule out edema/swelling as an issue as well. Your socks or shoes could be creating the rash on your feet more so if they got wet while wearing them or if you have changed soaps or detergents. If the rash persists or returns get examined by a doctor.

your sister could have eczema and allergic eruption or psoriasis.she needs to see a dermatologist for a diagnosis and treatment plan. Sometimes a skin biopsy is necessary.

I have patches of an itchy rash on arms and legs. When it started I thought it was ringworm but none of the OTC meds have worked. I have pics. Ideas?

There are lots...

Open-uri20130413-27587-97xihk
...of possibilities, but this time of year it is most likely to be an allergic response to something that came in contact with your arms, such as poison ivy, particularly if you've been working in the garden or camping or clearing weeds. Over-the-counter creams are too weak for such rashes, so let a dermatologist give you a precise diagnosis and treatment. Could we see the photos?

What would cause an intensely itchy rash on neck, arms, & legs?

Different causes

Itch
There are different causes of this type of rash includung allergy to foods, medications,etc. Have a physician or dermatologist evaluate the rash if still present. In the meantime if you're uncomfortable you could take Benadryl for the itch but be aware that it can cause drowsiness. Claritin is less effective but does not cause drowsiness.

I have a itchy rash for 3wks that I got from a body wrap. It started on my thighs and now has spread to my legs, lower back, and arms. Please help.

Use steroid cream

It seems you have an acute case of contact dermatitis and may need to see your doctor asap as it is spreading Meanwhile take over the counter Benadryl to control the itching and use 1%Hydrocortisone cream locally till you see your doctor You may need stronger steroid cream and/or oral or injecteble steroids

son has white spots on hands and fingers for about month. now itchy rash on arms legs?

Itchy White Spots

Dermatitis
This sounds like something known as dyshidrotic eczema, but without a picture or more description of the rash, it's hard to know. Would check with a dermatologist.

my Dad has had an itchy rash on his arms & legs for several months .. He got a cortizone shot, it cleared up & then came back. What could cause this He scratches till there are sores.

Eczema or contact

Open-uri20120915-643-1tk5vtm
dermatitis are the two most common causes of localized itchy rash. But Dr. Fisher is right: a picture is worth a 1000 words. If he wants a diagnosis along with his cortisone shot see a dermatologist or an allergist. The photo is of contact dermatitis.
