Rash on arms

[Roszak]

My son is 11 months old and the last few weeks he has come up with a rash all over his arms only.  Its not causing him any discomfort and its not itchy.  When you run your fingers over his arms its not smooth so the spots are raised and red.  I have tried sudocream but it hasn't cleared up.  Any suggestions would it could be or what i could do.  Many thanks in advance

How are you? Heat rash is also known as prickly heat and miliaria. This is usually seen in warmly dressed babies but it also affects up to a third of adults living in tropical climates or during hot, humid weather. This develops because baby's sweat glands are not yet well developed.Heat rash looks like a red cluster of pimples or small blisters that maybe associated with itching. It is more likely to occur on the neck and upper chest, in the groin, under the breasts, and in elbow creases.Most often, heat rash goes away on its own. Severe forms of heat rash may need medical care, but the best way to relieve symptoms is to cool your skin and prevent sweating.  Keep the affected area dry.Give him cotton-made outfits and use mild soap to prevent rash formation. However, if the rash persists and involves other symptoms such as  fever or severe itching, it would be best to see your doctor for proper evaluation.

I hope this helps. Take care and keep us posted.
