Rash: It sounds like you may have been exposed to a toxin such as poison ivy or oak. Try not to sratch the area. Take an antihistamine to see if it will help. Use Aveeno (oatmeal) in your bath water and try a mild hydrocortisone cream. If this doesn't help see your doctor for an assessment and consideration for steroids taken by mouth. All the best and I hope you feel better soon. ...Read more

Now &  then on backs of arms i get lots of tiny bumps almost like a rash with no redness or itching they hang around for few days comes & goes causes?

Possibilities: Could be keratosis pilaris. Are they firm bumps? If so it can be caused by keratin clogging hair follicles. Gently using a "buff-puff" or other time of mildly exfoliating cloth while in the bath or shower can help unplug the follicles; then pat your self dry and allow to air dry prior to using a mild retinoid; like retin a (tretinoin) which is a prescription or an over the counter retinol product. ...Read more

Circular rash: May be fungal like ringworm. You can try over the counter anti-fungal medications. or may be eczema due to dry skin or food /environmental allergies or granuloma annulare which needs steroids, sometimes you can first layer the antifungal and then on top the steroid cream or get a cream that contains both by prescription f/u /w/doc see http://www.cdc.gov/fungal/diseases/ringworm/treatment.html ...Read more

Red rashes on upper arms and buttocks? he hasnt been sick lately.he says that it doesnt itch& recently told dr said it could be eczema, what can I use

Doctor can examine: Rashes can be hard to describe or diagnose without seeing them. A primary care or a dermatology doctor can look at it in order to tell what it is. If a dry skin or eczema rash, hydrocortisone cream helps. Some rashes are an allergy to something. Hydrocortisone also helps allergic rashes. Bacterial or fungal rashes benefit from antimicrobials. If it doesn't go away, a dermatologist can take a look. ...Read more

Been on clonazepam 1mg for 18 months. 5 months ago developed rash in arms and legs,redness,eruption,dryness in legs. Should I quit the drug?

See your doctor: If you have already continued it for 5 months after your rash developed, I would not think that it is likely related, since it would probably have gotten MUCH worse. A health professional needs to take a look at your rash, get a full medical history and determine the cause. Talk to whoever is prescribing the clonazepam. You may need to see a dermatologist for the right answer. ...Read more

I have rashes/ hives on my forearms and shins at my sock line. warm to touch and really red. once got so bad on arms it created large 1in boils?

Allergist: I recommend that you be evaluated and treated by an allergist. You appear to be experiencing some sort of allergic response to something internal or external. I find these cases to be very elusive in finding the triggers and I feel that an allergist is best qualified to deal with them. In the meantime try an antihistamine like benadryl(causes drowsiness) or claritin(nondrowsy). ...Read more
