My two year old has a red, itchy rash with little white bumps that are elevated. It is spreading from legs, feet and shoulders to her back.  She had a fever this morning.  She has also been coughing more frequent in the last few days and is complaining of her back hurting.
Fever is likely to be due to some sort or infection. Fever with rashes and cough are frequently due to certain viral infections. The rashes could be due to an allergic reaction which is often seen in a viral infection. Although some antiallergic like cetirizine syrup and application of some emollient like aloe vera lotion should provide relief, I insist you to get the child evaluated by a pediatrician or dermatologist to find out the cause. Giving paracetamol should help in relieving both the fever and the backache.
