doc I experienced sudden itching all over the body but there were no signs of the cause as there were no red bumps
Thank you for the question.
Itching that spreads throughout the body most often indicates an allergic reaction. Indeed, not all people who experience allergies will also experience bumps or red spots on his body.
In addition to allergies, itching can also be caused by insect bites, hormonal disorders, psychological disorders, skin infections or other organ systems, liver disorders, kidney disorders, xerosis, atopic dermatitis, neurodermatitis, prickly heat, drug side effects, and many more possible triggers other.
Depending on the cause, this itching can require different treatments. If it is true that no other complaints have arisen, presumably your complaint can be alleviated first by:
Drink at least 2-3 liters of water a day
Do not scratch excessive itchy skin
Take a shower that is diligent and clean, use soap that contains moisturizer and salicylic acid
Dry your body well using a clean towel and soft fibers, before dressing
Sprinkle salicyl powder on your itchy skin
Wear clothes that are soft, loose and absorb sweat
Condition the environment where you are active so that it is clean, has good air circulation
Do not carelessly exchange personal belongings with others
Stay away from cold, food or medicine, as well as other things that make you allergic
Don't stress too much, increase relaxation
If itching becomes more and more, or other complaints arise such as high fever, rash or swelling of the skin, tightness, wheezing, and other danger signs, immediately check with your doctor or dermatologist for further treatment according to the cause.
I hope this helps.
