Itchy Rash

What is a Rash?

A rash is the abnormal change in the skin and this change affects the texture, color and appearance of the skin. The rash might affect an individual’s entire body or may be just localized at one part. Rashes can be painful and might cause the skin to become cracked, dry, sore or itch. Thus the treatment for rashes varies depending on different factors.

What is an Itch?

Itching is an unpleasant feeling in the human body that causes the reflex or desire to scratch.  Research has proved that itching has a number of similarities to pain but their behavioral response patterns are different. While itch leads to scratch reflex, pain leads to withdrawal reflex.

Itchy Rash Vs Non Itchy Rash

Rashes can be of two types, they could either induce an itching sensation or they might be non itchy rashes. While conditions such as goose bumps, roseola, skin tags and warts are non itchy, conditions such as bumpy hives, folliculitis and acne are itchy in nature. The severity of the itching sensation varies from disorder to disorder. For example, a person suffering from severe psoriasis will suffer from itchy rash condition where as an individual suffering from mild psoriasis may not feel the urge to itch. At times, severe sun poisoning condition also might lead to itchy rash condition.

Coughing is a way by which the body removes foreign bodies from the human body and keeps the throat and airways clean. However, many a times, coughing is a symptom of other disease or disorder and it is very important to know how to treat a cough. Coughs can either be dry or productive. Productive coughs are those that bring out mucus from the body. The mucus is also known as phlegm or sputum. Depending on the duration, cough can be categorized into acute coughs, sub-acute coughs and chronic coughs. Chronic coughs could last longer than 8 weeks whereas sub-acute cough and acute cough can last for 3-8 weeks and 3 weeks respectively.
