Doctor can examine: Rashes are hard to describe in words. Usually, a doctor has to look at a rash to decide on a cause. For common rashes such as eczema, mild reactions to plants or chemicals (the soap?), excessive dryness, or little itchy bumps, the doctor may recommend over-the-counter cortisone cream two or three times a day for 1 week. For fungal infections like t. Versicolor, selenium shampoo may be recommended. ...Read more

My niece is having the problem of fever and she got rashes on her full body everyday and taken medicine also. Paracetamol and cetirizine suspension.

Doctor can evaluate: Children's fevers are often from infections. Germs such as viruses and bacteria interact with the immune system, resulting in fever and sometimes a rash. Fevers may also occur from non-infection types of illnesses, but these illnesses are uncommon.

I had a full body wax for the first time. I have broken out into very large rashes including on my arms groin and entire buttocks. What should I do?  

Time, cold bath: It's much more likely to be from the trauma of having your hair ripped out than a potential allergic reaction to the waxing product. This will likely improve over anywhere from a few hours to a day or so, and a cold-water bath or shower may feel good and relieve some of the redness/pain. Creams/products are unlikely to help a rash of this type. ...Read more

Past three days been extremely itchy all over body, primarily arms and legs. No rashes, etc. No new changes at all. No allergies. What can be cause?

Past three days been extremely itchy all over body, primarily arms and legs. No rashes, etc. No new changes at all. No allergies. What can be cause?

May be hard to find: About 50 % of cases of itching without rash, one is not able to figure out the cause. Of course, the common allergens are something inhaled that the histamines in the body react to; or some new perfume or scented lotion, deodorant or something else new used on skin. Suggest taking an otc antihistamine daily, take only lukewarm showers. Will likely go away in 2-3 weeks. If not, the usual: c the doc. ...Read more
